This question takes on almost metaphysical limits.
Anger: At the world, which is such that it continuously enjoys the suffering and exploitation of others and at the same time justifies this behind the supposed common good of a few.
Revenge: To anyone who has not only kicked me in the face, hurt, insulted or humiliated me. As that could be forgiven and forgotten. But that behind it hides a greater evil, that is out to constantly enjoy the suffering of others, only to enrich themselves personally. This is something that I can hardly bear, or rather not at all.
But I am not talking about an ominous evil, or a questionable morality alone. I really mean the human system as such, which (in my opinion) has not really developed since antiquity. Basically, only the welfare of those who are at the top anyway is favored, meanwhile the people are satisfied with bread and games. Replace bread with social media, and games literally with any mass event that serves to direct the emotions of larger crowds in a certain direction. One can certainly look at the problem from different angles of perspective at this point. The bottom line, in my opinion, remains the same: The many stupid, poor people have to bow to the will of the few rich, powerful ones, because they shape the world for us poor lunatics/peasants.
And with such a world view, which is to be glossed over in my opinion at most in parts, one is not to despair as an individual and become ill from it? What is here the really sick and (forgive me if I say this) crazy? The world? Or us? We who have to live in such a world. And “supposedly” have to adapt.
Just as I don’t feel like killing myself, I won’t submit to this world, or even adapt. Rather I remain (at least) eccentric, than that I accept this global lie of the unchangeable. Rarely is it the many few who need to change, who simply want to live. It is those who are supposedly in charge who need to realize their error and change. Only in this way can peace come about. Or war.
Unfortunately, and this is the bitterness behind it, ideals are recognized quite late. If at all. Therefore the human life is constantly in the change, fight and the social society aberrations.
At this point I would just like to mention that I am of course writing this from my very German language, and not everything is translated 1:1 into English. Not that I claim that English is a rather “simple” language here. But even the best translator and my own language skills may not be enough to allow my very talkative mouth to the full extent here. I’m sorry for that. In my mother tongue, many things might make a little more sense. ;-D
