AITA for wanting to play Fortnite?

My mum (82F) told me (12M) to do the dishes (16) but I (12M) was too busy playing Fortnite (3 kills) so I (12M) grabbed my controller (DualShock 4) and threw it at her (138kph). She fucking died, and I (12M) went to prison (18 years). While in prison I (12M) incited several riots (3) and assumed leadership of a gang responsible for smuggling drugs (cocaine) into the country. Reddit, AITA?
