abiather Your metaphor about pilots that bombed Japan is problematic to say the least for it doesn’t address the inconstant logic of your statements. Many who go to war think rightly or wrongly, that right is on their side and put their own lives at risk for people or a cause they believe to be worthy of such personal risk. That in itself could be thought of as the very epitome of altruism.
What people do and why they do it cannot be separated as easily as you imply even though one can be ostensibly good while the other not so much or the other way around. Take abortion for instance, as you mention it! There are reasons why abortion is a good thing; say for a mother who will die if she does not have one for medical reasons. Whether this is a good or bad thing for the embryo and at what stage is up for debate but on balance is will be a good thing for the mother and her existing family.
If you ask atheists why they are atheist, I suspect that none will say that it was because they wanted to escape personal responsibility and therefore changed what they thought to be true, as though choosing one sweet over another in a candy store like the changing wind. As for theists they mostly believe because it is what they were taught to believe by their parents. Again it seems to be not for trying to escape personal reasonability.
You are conflating motive with action and action with consequence and then categorising consequence according to the human concept or right and wrong. This concept does not really exist in nature except in the basic forms of decay and order without moral judgment. In people good motives can give rise to actions and these actions intended to be good can result in bad and vice versa. Actions intended to do good do not always do so because life is more complex that you posit. There is a of course a general correlation between actions intended to do good and good outcomes but over time this effect is always naturalised. Those who feed the poor will eventually die as the poor also will, only to be replaced by new poor and those who wish to help them.
For your position to be having any kind of merit you will have to demonstrate why the effects of entropy and decay will not affect your good works or whatever it is you are trying to preach? You will also have to take into account basic logic and reason, which as yet you dont seem to be doing.
