The most adult conversation we've had so far

I'm fostering a 20 year old. He has had a really rough life. He got take away from his parent because he was being abused almost died at 5. Got adopted at 11 and then taken away from that family at 14 because they abused him. And he's jumped around the system since. I've spent time helping with his therapy. I've tried helping him with adulting but it's been hard because he age regresses. He was outside in the cold vaping. I brought him a blanket and sat outside with him. And he opened up for the first time and said his mom called. I asked bio or adoptive and he said bio. I asked what she wanted and he said "What she always does. To vent about her life like the past never happened". He then asked me "Why is the world more forgiving of mother's than father's?" I asked him to elaborate and he said when he tells people he was abused by his father people feel bad for him but when he mentions his abusive mother people tell him she still loves him and to try to make amends and mother's make mistakes. He also said the term mother seems to be a loved term. And that mom's are seen as these people who are supposed to take care of you and he's had two and wasn't worthy of love from either. He told me when his dad beat him it was out of anger. But for his mom it was out of joy and she loved it. So he said "Why is the world so forgiving of mother's?" I said something along the lines of "Well, there are mother's who would sacrifice anything for their children. And people who have mom's who sacrificed everything. I think for some of those people it's hard for them to wrap their head around a mother not loving their child how they're supposed to. So they think it's impossible and she just needs love and support to change when in reality some women just shouldn't be mother's. Some mother's are evil". He then told me "I don't want another family. I've had two. I'm not meant for a family ". I said "You deserve to be loved. And even if I'm not your family. I'm your friend". That was the most adult conversation we've ever heard. The first time he's ever opened up to me❤️
