Rant, child neglect??

Here we go: so I am temporally living at my brother in laws house with my fiancé because we just moved here and are getting our own place. His brother and his girlfriend have young 3 kids and I am appalled by now they raise these children!! No hot water in the house, no kitchen sink which resorts to washing and then leaving dishes in the only bathtub with food in it, NO food, no washer or dryer so the kids wear dirty clothes that smell like piss to school, the mother and father sleep all day long, father has a job but "doesn't feel like going to work", how pathetic is that?! The kids come to me when they are hungry and thirsty while their parents lay in bed all day.there are piss ridden clothes all over the bathroom and now there are bunches of flies everywhere! On top of the dishes and food rotting! I've never seen people live like this!! Oh and no toilet paper ever. I am moving out asap, my man and I didn't know it was so bad..it looked nice when we visited.. If it wasn't for my food stamps idk how these children would eat some nights. Should I report this or would that make me a bad person cause its my family? But I am sickened how they live. Someone could get a job! How can people do this with 3 kids?? Ive never seen people do this, idk if I am over reacting. Thoughts? I have no children but I know MY babies wouldn't live this way.
