Rewatching all Seasons to better understand the whole story because once wasn't enough I didn't absorb each episode properly. Currently finished this episode though and it's got to be one of the best episodes in the series. Plot, Character Development, Morals exceptional. The creators have done a good job this episode by exploring Kenny's backstory I thought just enough was provided. It would've been cool if he recovered somehow and was given a chance to atone for his sins by joining Levi's squad like how Commander Irwin did with Levi in No Regrets and I know he killed a lot but let's be honest he would've been a great asset to the team.
