Because i smoke cigarettes, does that make me a bad kid?

i just moved out of my moms house because she disowned me, i now live with my uncle and his girlfriend. they have a baby together and they both work from 8 to 5 and they have the girlfriends mom take care of the baby and cook for them when they get home. i help cook, take care of the baby, clean kitchen, clean dinning room, clean bathroom, clean living room, take care of the garbage, and help with anything extra they have me do by the way im 16.. They dont thank me. I dont get any money to spend with friends. And they think i dont appreciate them because i smoke cigs. Am i bad kid?
