Is it wrong to want or seek vengeance on a girl who did me very dirty?

That's not vengence. That's revenge which is petty. Vengence comes after a group of people want revenge for multiple years like in a vendetta.

Or with fueds. You got vengence. You left his class.

But if it effected you permanently like, prevented you from walking with your class when you graduated. Wait until you succeed then go. Otherwise you won't be able too, they will be too strong.

If it's worth it then, by all means find them and "talk to them". Literally, sometimes it has to work like V for Vendetta. It's not like V wanted to wait for decades to cause a revolution.

He wanted it then. But he actually couldn't because the strength of the enemy was secret and hard to destinguish plus, if you make one mistake, the game is up.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
