It helped me a lot to fully internalize the reality that every person is truly doing the best they can, given the genetics and environment they were dealt by the universe. There's no reason to feel hatred towards any person for being flawed. This applies to yourself when you eat too many donuts as much as it applies to a serial killer that tortures people. It simply doesn't make sense to feel loathing for anyone. Pity is the rational response towards the flaws of humans. This doesn't mean people can't be improved to a large extent with an improved environment. This definitely works, which is why some self-help books work for some people or why joining the military can help some people improve themselves. This realization also focuses your efforts on the environment (food, sleep, exercise, books, etc) which is another great aspect of it. Knowing that the way to improve a person is through environment removes the shame of failure. The answer is always to improve the environment and never to blame the person for not being better than they are genetically. Blame the environment for not being good enough to help the person, and then improve the environment until it is.
