AITA for killing my entire fucking family?

I (24M) was playing on my ps4 (slim) during a family gathering (2:00-7:30) and was playing cod (black ops 4) and was playing an intense match (online free for all) when my mother (69F) told me to go downstairs and socialise (with family). so I (24M) said “fuck off bitch” and my mother then decided to unplug my ps4 (slim).

in response, I decide to throw my controller (duelshock 4) at her head (large) killing her instantly. I then load a gun (454455556655445M) and fucking kill(shoot) my entire family (22 people) to death

the police (34M, 56F) are currently calling me an AH but I think that my actions (multiple counts of homicide) are correct.

so Reddit? AITA?

edit: the police have shot me 16 times. (torso) I am at the hospital (69420) and am waiting to go to court. considering suicide(good)

edit2: I commited suicide (hanging) in my jail cell. thanks for the advice guys👏👏
