I don't really get this question. Draco would have got better if he didn't save Harry - how? At what point?

On the last movie draco jumps to save Harry

Where does he jump to save Harry? I don't get it.
He only helped in the last book by pretending he didn't know if it was him when Belltrix was asking him. The help was very small. And in return Harry saved his life from the fire.
He would have had a miserable life under Voldemort's rule and I think he's having a decent life now since Harry defeated Voldemort.
Anyway, I don't understand the question but I guess he's better off helping Harry.

I couldn't remember a scene where Draco jumped to save Harry either.

Its in the part two

Thats what my sister a told me

what? He didn't help him.
