opinion: Shepard Renegade is more realistic considered the situations that he came into

don't you think the renegade Shepard is more realistic in many situations (expecially in the 3), I mean you're looking at an ultra powerful species that wants to exterminate quite a number of species in the galaxy... as nice as it would be to save everybody... it's impossible...

of course I exclude really evil situations like the genophagy cure, that is pure evilness if Wrex is in charge (in the case of Wreav... let's talk about that).

with this i don't want said that played paragon is wrong, i only want hear your opinion about this.
