No, I'm not saying capitalism creates honest people... I'm saying the philosophy itself is being honest. Communism says once it gets into place, we're all just pulling for the common good and everybody gets equal ownership of everything. This is a lie. The system still "inherently allows others to be dishonest without repercussions, accountability, responsibility, etc.", and history can make a good case that it does so all the more so than a capitalistic system does. Capitalism tells you the truth; it's a rough world out there and you need to be able to find some way to compete.
Much of the criticism (but not all!) of capitalism boils down to people shooting the messenger. It is a rough world out there and you do need to find some way to compete, but some people would rather hear from people singing about how if you just give them all the power, their philosophy will erase that from the world and you can just go to sleep peacefully and stop worrying. Unfortunately, this is also a lie, or at least that's what the history shows.
Nor does this mean that we are somehow obligated to "maximize" brutality or something stupid. It means that by facing it squarely, we are better able to deal with it, and that's why the capitalistic countries of the world are far better places to be than the places that reject it. It may not be perfect, but by aligning oneself with the true nature of the world you end up producing enough excess wealth to be able to seriously engage in social programs. It's OK to wish it weren't this way... it's not so OK to think that if we just close our eyes and wish hard enough we can make the problem unexist. That leads to actions that leave you vulnerable and exposed. Facing the truth is part of the path to changing it; denial often just makes it far worse.
Where both Communism and Capitalism betray their fundamental nature as ideological is where they attempt to predict the future, or divine the behavior and/or motivations of their participants.
EDIT:

That survival depends on competition is a religious tenet, an ideological rationalization.
Survival depends on you being able to compete in some manner because resources are finite, and for every life form that lives there are thousands, millions, maybe more that don't live because that life form had the resources. The idea that humans are somehow excluded from that is itself a religious tenant or rationalization, or perhaps more accurately, an illusion brought on by this moment of overwhelming wealth and power humans have amassed for themselves. For this brief moment in geological time, it is possible to successfully "compete" for resources by, for example, drawing this bizarre thing called a "disability claim", which hasn't exactly been around for very long, and has no guarantee that it will be around for any particular period of time into the future. But you can only do this because of the wealth generated by the incredibly successful competition that humanity has developed... and it scares me both that the boundary between this life and the more normal order of affairs is so thin, and that there are people, like you, who treat it as some sort of natural law, to the point of mocking people still in contact with reality. History shows when there's enough people like you, the prosperity goes away. Alas, history doesn't show us a way of preventing that from happening... here's hoping the march of technology gives us an exit this time.
It is a wonderful thing that humans cooperate enough that we can build enough wealth that some of us, even many of us, can forget this... but the fact that the human strategy is ultimately one of great cooperation doesn't change the fact that the human cooperation lives on a substrate of vicious, no-holds-barred competition, induced by the physics of how this universe works.
Realizing the world is built on competition is not what breeds viciousness... it is what lets us successfully build the secondary layer on top that shields us from it. Those philosophies that try to take a shortcut and declare that the world is not a competitive place have the paradoxical effect of exposing us all the more directly to the raw competition again, because it causes people to build structures that, in their denial of the nature of reality, therefore fail to insulate us against it.
The first step to solving a problem is ever and always clearly identify the problem, not refuse to see the problem.
It's all so clear isn't it? However, the "this is it; this is the answer" mentality that you express here is yet another instance of ideology and zero-sum thinking.
Long story short, if you're talking about a secondary layer over anarchic brutality, I'm talking about tertiary-and-beyond ones. Obviously this is no natural law, much less than your secondary layer. And I never said that competition breeds viciousness, but if you want to argue that point, I'll take the position that your secondary layer has not eliminated it.
The first step to figuring out if you've identified a problem properly is to figure out whether you are soaking in it.
I would like to order one infinity of energy from you, then. Please deliver it to my email address, as I'd rather not actually receive it directly to my house.
I'm actually the first to say that A: it's all energy and atoms in the end and B: the universe is awash with both and it's mostly our own stubborness that prevents us from claiming both since we don't "like" nuclear. However, even a Kardeshev Type III civilization will have to contend with the fact that its resources are finite, and as rapidly as its ability to exploit them grows, its desires are likely to grow even faster.
It's not capitalism that causes that, either... a great deal of our desires expanding faster than our resources predates the entire concept, and the problem will likely outlast it as well.
There is nothing wrong with desire, in fact desire is good. There is problem with non-sustainable practices that damage the environment which includes people.
What you're stating as an issue comes down to management, resource management and people management. Capitalism has played a role in allowing us to see what is possible when we allow people to pool large amounts of resources, when people's efforts can be directed towards a specific goal - incentivized by the organization's leadership to aim for profits. Money is a concept which is important to remember when we're talking in theoretical terms. Money is time, time is money. What can we do with unlimited money?
