Ah- yes, a very valid possibility. It's always possible to go too far.

[Loki knows. It's one of the reasons he's reluctant to magic his way through everything; that could well be too far for him, send him back to chains and fire.]

I have no real solutions to offer you on that one, save the reminder that most of the people you'd be upset about getting hurt will also get upset if you don't go far enough and get hurt in the process.
