I'm curious to know why you think that Conner could never be like Superman? Superman has gotten the "Blue Boy Scout" bad rap for decades, but I honestly believe that it would be harder to be that kind of hero than the anti-hero type. It's easier to give into base desires and mete out justice in one's own fashion than to take a higher road. Why would it be so wrong for Superboy to want to aspire to that level?
I consider making the hard decisions necessary and living with it, as the higher road. The lower road is capturing a rapist/murder etc, locking them, then they get out by whatever means, kill and commit their crimes again, and then the people's champion repeats his steps all over again. Saving innocent lives by whatever means necessary is the higher road.
