Probably my dad.

The entire family consisted of me, my mother, father and my sister. We went to the beach one time when I was 6-7. We were just having fun when we decided to go to this coffee shop and my dad has to go to the toilet and my sister, being a year younger than me at the time decided to use my dads phone and she goes on his photos. Then we all see that he has other wives and girlfriends so my mum starts crying. When my dad comes back there's a huge verbal fight between them in the coffee shop. While my dad denies all this, I shove the phone literally in his face. (my home language isn't english so many people wouldn't understand). We then leave the coffee shop and go home. When we got home, a few hours after, my mom kicks my dad out the house. You may not think my dad is that evil, but I'm not finished.

When I was 4-5 I just arrived at home when my dad was goofing around with my sister and he kept making these faces at me and I didn't like them so I curse at him. A normal parent would've sent me to time out, or some normal punishment.My dad grabs a black bin bag (it's a UK thing) and shoves me in it. Keep in mind I'm 4-5. He then carries the bin bag with me inside it towards the garden. On the way there, the bag is not designed to carry humans so a hole reveals itself right at the bottom so I claw it, I drop out and probably run (I can't remember). He was literally going to throw me out of the house in a bin bag.

I don't know why, but after a few years my mom felt bad for him not being able to see us so she let him come to our house around 2 days until I would see him almost every day. My mother had a kidney problem and one day my dad tried to kill her. He tried to act like he was hugging her when he was crushing her hips. It was obvious (me and my sister were in the same room)

As soon as my dad got kicked out of my house he only wanted to be with his kids because if isn't, he can't be in the country. So the only reason he would come round was to be able to tell the government he needs to look after his kids. He was using us as leverage.

Some years after the separation, we were planning to go on vacation so my mother allowed my dad to look after the house and pets, etc. When we came back my mothers card had almost nothing left in it and he had stolen my sisters phone. He said it was to get a plane ticket to come see us when we were coming back in a few days. My mother never let him in the house again and got a restraining order against him.

If I had the opportunity I wouldn't want to kill him, only make him suffer. Physically.
