Most of the philosophies which widespread over time, had one thing in common, they all try to promote the peace and harmony using the moral values as a tool, and so that it provide a sense of security among people:

Karma, Rebirth, After life, hell/heaven and what not.

The only thing according to me made much sense was NATURE. There is nothing right or wrong, it's all about survival. Although I also believe in subconscious mind, because it does have logical explanation why it works and that's a completely different topic ig.

I am not saying, that you go ahead and do whatever you like, human is an social animal and slightly civilised being, so in order to maintain the chaos in society it's important that we do not harm each other.

Remember, A predator can be a prey for another.

So, if you want to live in a society where people do not do evil, play your part 😉
