Not sure if impressed by the savagery or disappointed that kung-fu Krang isn't a thing anymore.
Also, while I'm pretty sure the work itself is acknowledging that the MC is ruthless in a way that stands out from the rest of humanity, it would be nice if it took some tips from Japanese fiction and did some stylistic indicators of the sudden shifts in mood he's causing. Doesn't have to be comically extreme the way it's usually done, but a slight shift in panel colors or the way the MC is framed would do wonders, even if left really subtle.
