Wow, shock news, the boy was just doing what anyone who is sexually active wants to do, and that's having sex. It's not his fault that him and the girl were given inadequate sex education. So why is everyone calling him and his girlfriend douches? Sure, that's a word for their parents, but not for them.
I also think it's a bit early to write them off as a drain on society. He seems to be coping pretty well with fatherhood - taking it in turns to feed the baby and saying he's going to try and be a good father - which is more than many adult fathers say. Of course it's not ideal to have a child at that age, but maybe the experience will turn him into a responsible adult, in which case he'll be able to repay the money that's been invested in him by the state when he goes out to work.
He's certainly been no more irresponsible than, say, Sir Fred Goodwin, and possibly a lot less. At least he's contributed a new life to British society, and may yet contribute more. Goodwin has been a COMPLETE drain on the state.
