Snatching a phone or bike and riding off because you're poor is "fine" - no one is really hurt aside from financially, and if I had to have a proper crime committed against me, an involuntary donation of a few hundred pounds (i.e. my phone) to a non-violent poor person is about the best one I could pick.
However, disfiguring someone with acid shows a level of callousness and sadism that means you aren't safe to be around other people, and no one should be attempting to excuse behaviour like that. A lack of opportunities doesn't give you the right to ruin someone else's life forever.
