Moralism is liberalism. Material conditions create people not the other way around (although people are a part of material conditions). Stop wondering if people are "good" or "bad" and think about if they will rise up in opposition to you, if they will help you, or if they will passively accept what comes. The vast majority of people will fall in the last category. Only hate your opposition because they oppose you, not because of what they are. Change the material conditions and you will change the people.

Misanthropy, anti-natalism, nihilism, etc. are all metaphysical bullshit. Purge yourself of it and you will be a better communist.
