full of pain(s)

Can you correct my grammar and style and word choice?

-Life is full of pain(s) and misery(-ies). Sometimes you do not want to offend other people, and you just want to be a hermit, secluding yourself in a small corner, and paying no regard to the storm outside the tranquil life you are living/leading. However, some people are aggressive and extorting, which nature in their character(s) drive them to deprive/exploit others of their in-born rights and freedoms. They then become vengeful. Giving up revenge would occasion indignance; harbouring retaliation intentions would vitiate/weaken/shrink/impoverish attention that could be employed to seek happiness. This dilemma brings human beings agony(-ies) and anguish(es).
