Seems easier to just kill him and take his broken gem, since they seem to be able to recognize familiar gems. They'd still get the reward, YD can still publicly crush Rose's/Steven's gem; which seems to be the worse thing a gem can do to another gem.

I doubt YD had plans for this, Japser's remark was more of shocked curiosity. Regardless, the question that prompted this was, why did Jasper take her helmet off? If keeping her helmet on neither kills or poofs a gem, then why bother taking it off when she got to Steven. Since she believed him to be Rose, and her previous statement was something along the lines of beating Rose up. So your analogy about the princess doesn't make any sense if headbutting him with the helmet won't kill/poof him.
