AITA For Trying To Make My Son Try To Kill His Half Brother? 

AITA for trying to make my son try to kill his half brother? 

i (1000+X) tried to make my eldest son (150M) kill his half brother (15M) and now they both want to kill me. 

i’m a sorcerer, but i’m a bit of a mad scientist as a side hustle, and i like to perform experiments for fun, especially on other sorcerers. 150 years ago, i created 9 cursed spirit-human hybrids. up until a few months ago, they were all kept in tubes in a high school basement.

in the mean time, 16 years ago, i discovered that the soul of my old frenemy's (1000+M) twin brother that he consumed in the womb was reincarnated, so i had a kid with him too, my youngest son.

this year, my youngest son ate a few of my frenemy's preserved fingers, so my frenemy was living inside him, in a sense. in an effort to make contact with my frenemy for a new experiment which i cannot reveal at this time, i stole three of my older sons from the high school basement and let them out.

my youngest came into a conflict with the younger two of the three sons i released, and he and his friend (15F) killed them. my eldest seemed really upset, even thought it didn't seem like that big of a big deal to me. later on, i lost the need for my frenemy's help, so i told my eldest he could kill my youngest to avenge his brothers.

somehow, when they were fighting to the death, my eldest realized that my youngest was his half brother. he ended up having some kind of mental breakdown and didn't kill my youngest. now he's mad that i tried to make him kill his brother, which i don't really see how that's relevant to the situation.

every time i've seen either one of them since they fought, they've tried to kill me. i don't really know what i did wrong. i'm just investigating the nature of sorcery, my life's passion. honestly, i wish they would show more respect for me as their parent and not jump me every time they see me. AITA?
