I'm wanting a pacman frog but I got some questions?

I am thinking of getting a Pacman frog (Because of Pacman and I love animals) and I'm wondering what do they eat? I will NOT feed a animal to another animal. I can't do it...I can't kill a fish or a mouse. It's not in my nature. Anyway do they make good pets? Can I just give them cooked chicken? What do I need to put him in? Are they abit loving? Do they scream all the time?
