Mega Man X was the first, fully sentient robot. The original Mega Man still has to follow his programming. To do otherwise would have consequences (logically). In this case, technically, he'd have to give blowjobs if that were, indeed, in his programming.
Something tells me it wasn't, and that really was Roll's true purpose. Dr. Light looks like he'd be a dirty old man. He has dirty old man beard (even if Dr. Wily does rock a better pair of "creepy uncle eyes").
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
