Y'all I am confused about some stuff:
Is makima the domination devil herself or did she had a contract?
Also, what's her deal??? First she takes control over denji, then makes him go berserk and then she wants to kill him-? And she says it like, ur not the real chainsawman blah blah-
The weapon devil hunters don't die or wot-? Istg before the last denji vs makima I saw them die thrice already.~ and if they could be revived why not beam?

I think she's the domination devil herself. So everytime she dies or get hurt, the damage is inflicted to humans that contracted with her or humans that are being dominated by her. The weapons devil ends up being revived by her since she's the one that technically killed them. Beam's devil could be revived in hell I guess..

Yeaa they came back cuz makima killed them, therefore she can summon them back. Quanxi, angel, aki didn't die in that hell. She killed quanxi and then made angel says that he'll give everything to makima. So basically quanxi and angel already being dominated by her. As for the katana devil and other, I'm so not sure

Hmm I'm not so sure either but I think she wanted the devils that she dominated to not disappear. Like I think there's some parts where she renamed the devils that she had killed when she revived them and she also mentioned that devils that are eaten by chainsaw man, their name stays (stays feared I guess) so she wanted chainsawman to eat her so she would stay be feared. But then when chainsawman grows weaker and become more like denji she thinks that (maybe) chainsawman should just die since he already weak and got no worth for her anymore (since she wanted a person that is at the same level as her not lower)

Ayo someone tell me what did they gain from killing MC's brother?

At this point of the manga - They killed Jeong-woo cuz He was the leader of Arthia. Arthia was relatively a small rookie clan, but despite that it became a very successful clan. The other major guilds (8 clans) joined forces in order to destroy Arthia. + Jeong-woo was considered as a strong AKA a threat.
In the future - spoilers - no comment from me now (If you want some spoilers just ask though).
It hurts whenever he misses/thinks about his sister
