I was in the foster home at age 14

The guy who ran the place was a pillar of the community, an architect, although completely talent-free

He was abusive and cruel to me

His wife was a hillbilly of sorts

They stole from me and would not ever allow me to spend time with family friends

He would drag me out of bed and force me to play duets with him on piano while he played a rusty old baritone

He smashed my possessions

I tampered with his medication, dumping contents of thyroid caps and replacing them with Potassium-K and pentobarbital

Weeks later, his heart stopped on the basketball court

I watched him struggle, then die

I urinated on him, then called the EMT unit.

I never got caught. I believe I did the right thing even now
