This writer at Forces of Geek suggests what a person should really do if he or she is gifted with the abilities and resources attributed to Bruce Wayne, better known as Batman.
The upshot is that Batman's decision to don cape and cowl, create fantastic gadgetry and pursue a one-man obsessive war against crime in Gotham City does not maximize those abilities and resources. The writer lists four things that he could choose to do that would have a better impact on Gotham's crime rates than polishing off thugs with a well-aimed Bat-boot to the head.
He is probably right. Any of the four suggestions at the link would be wise choices. The problem is the one he leaves out, the fifth course of action that would accompany any of the others: Be boring. Be really, really frickin' boring.
Because I have it on the authority of numerous internet memes that if one has the option of being Batman, one should always be Batman.
