Interesting viewpoint! I'd debate a couple of points, though.
1. The Rikti situation was a complicated one. It may have been that only Galaxy Girl was in a position to help without just being instantly cut down. As she had been in retirement up till this point, Statesman may not have known of her being in a position to help, or even that she was in the fight. Recall that "chaotic" is a term frequently used to describe that first desperate battle.
Overall, the fact that Statesman was unwilling to (as he saw it from his position) throw away the lives of the heros he was leading in a personal bid to save his daughter actually compliments his character instead of tarnishing it.
2. Delving into genetic manipulation is an extremely controversial subject even in the best of times, and when you're talking about the kinds of powers metas can have, it's not surprising that people are hesitant to open that can of worms.
As for his "world control," Statesman is not Tyrant. He doesn't rule anyone, and he doesn't levy consequences against people or organizations for merely disagreeing with him.
Finally, none of that is an excuse for becoming what Vahzilok became. He was already unstable, and the death of his father tipped him over the edge.
3. Blue Steel is most closely associated with the PPD, not the Freedom Phalanx. If anyone was giving him a pass, it was his buddies on the force. Not surprising, given that the Clockwork had already killed some police officers at that point. Doesn't make it right, but also not really fair to dump at Statesman's feet.
4. Statesman WAS definately too confident in his abilities at the point when he died. Surviving a tactical nuke to the face (and 70+ years of fighting crime, supervillains, and aliens) will do that to you. However, trying to handle a threat alone doesn't make him not a hero. If anything, it shows he was trying to protect others by not getting them involved. Still not a great trait to have, but not uncommon among heroes, either.
