I wish I was a better human being

I'm not and I don't feel good about myself. I can try to be good, but there are people worse than me who don't feel half as bad about it as I do, who will take advantage of it.
I try to be a good person to the people I love, but when I do morally questionable things to people who deserve it, I feel bad about it later.
I feel bad about it, but I later realize those people deserve these things done to them because of how badly they treat others.
Perhaps I am not entirely bad deep down, but for me to be better, the world needs to be a better place. But it's not.

So, I suppose I'll get used to it. I already have.
