Would u help this mom?

So my friends sister is having another baby. She has nothing. Shes living with the guys (he beats her too) elderly family member sleeping on the floor. She has another child that she doesn't have custody of and never fought for him. Just moved away with a new man and left her son behind. Always ditched him as a baby (we ask her mom to watched him for an hour and be gone for 10 hours).

Her and her bf don't work. Don't try to. He sells stolen goods. She has smoked her entire pregnancy. She's just an awful person in general, even before she had kids. She really has no right having this baby she's literally not competent enough to be blunt about it.

My friend is asking me to help her out but I honestly just don't want to because the situation is so bad. And I know her bf is going to sell half of what they get from donations from people.

Would you help? Typing it out it makes me sound shallow or whatever but it truly isn't even safe for this girl to have this baby and idk I just don't feel right about helping someone like that that I can't trust if they will sell stuff. What would you do?
