Perhaps he never could "catch up" to the Coopers. Another thing people seem to believe is that Clockwerk killed every Cooper throughout history, or at least many of them (I admit to believing this at one point); however, he didn't kill anyone that we know of. Conner was killed by the Panda King, and while we don't know what happened to Sly's mother, we can assume the Panda King, or possibly Muggshot, killed her, if she wasn't already dead before that event took place.

Clockwerk is definitely a criminal (incitement to commit murder), but he never actually got his "talons" dirty (except for trespassing and theft).
