I need to find the name of a horror movie

I am here to find the name of one movie series. The first one was in an asylum at the beginning, and there were some crazy people, and a few kind in an asylum. One kid poked his own eye out with a fork and ate it as part of his back story, and then at the eye of a guard. At one point someone was killed with a defibrillator, and the main character had to hide under the bed. I think the 2nd movie had a girl get his arm cut off and the main bad guy, who wasn’t deformed bu the others were, said “Give me a hand.” and one of his goons gave him the literal hand and he was mad lol. I need to find these movies pleaseee
