Bad Seeds or Poor Gardening?

I had the oppurtunity to re-watch "Boys Town" this weekend (and I took it). While the movie is fantastically done with both Spencer Tracy and Mickey Rooney (who doesn't love the young Mickey?) and the true story is equally heart-warming, I couldn't help if there was a bit of a fallacy in Father Flanagan's theory that there are no "bad boys." Basically, he blames the ills of society and tough breaks in life for all the boys' misbehavior. I just wonder if in today's modern thinking we could claim the same. Are there sometimes merely bad boys, or bad seeds (another good film)? If we are partly nurture and partly nature created, then is it not possible to be wholly bad? Or do we always choose our evil? Very perplexing indeed...

Another puzzling thought: Did I choose this outfit organically, or did the ladybug discovered in my room this morning influence me unduly?
