I'll help, not because im that nice or something but because afterwards i'll be able to say to myself and others that i did something others couldn't. I'll always seek such stuff even in such situations XP Thinking carefully, helping an enemy like that would be helping myself. Without an enemy who would there be that'd push me to develop further in order to beat him. It also ensures my victory over him because afterwards the chances are he'll likely give up over me or i'll get the support of the audience.
