Sean Taylor was not a criminal. He did not have a troubled past. He was charged with aggravated assault by an over-eager DA who was later effectively removed from the case. Shortly thereafter, the new DA dropped the aggravated assault charge and Sean Taylor, though protesting while claiming his own innocence, was willing to accept a NO CONTEST plea (like you do with traffic tickets) to misdemeanor simple battery and misdemeanor simple assault. The defining elements of those crimes are the LACK of a weapon and the LACK of serious injury to the "victim" who in this case happened to be a guy that robbed Sean Taylor.

Regarding the DUI attempt, one judge dismissed the charge outright after watching the roadside sobriety test. The Refusal to Take a Breathalizer charge was dropped on APPEAL by Sean Taylor after another judge concluded that the arresting officer lacked probable cause.

Outside those two incidents, there isn't any reporting going on of Sean Taylor "embrac[ing]" a violent world outside his passionate play on the field that frequently got him in trouble with the league. But you can't just substitute spitting incidents and hard hits on the field as evidence that he "refused to divorce himself from" a violent past. It is a game, albeit a violent one, and Sean Taylor played it correctly.
