She did murder the baby, and horribly, and for that she needs to face the consequences.
I am quite surprised by the judges remarks about her having people to turn to who would have supported her though.
When I was 15, I think my parents would have supported me. But I absolutely would not have thought that they would have. She says she slept around at 13 to feel good about herself - I don't think that correlates with a girl with the sort of homelife where you think your parents would support you with birth/abortion etc. And her (step?)father was dying too.
I just think it's an odd conclusion to draw that her family would have seemed an obvious form of support to her from the limited information out there.
