I haven't played the game, but from the sounds of it you suicide yourself to collect a crystal. I'm going to assume there a penalty for death and that's what you pay for taking the easy way out. That isn't any kind of super exploit, it's just a way of playing.
An exploit you should feel bad about using is something like wall hacks in Counterstrike or duplicating items in an MMO. What you're talking about it simply strategy using the game mechanics.
