no.. Rocket is the very definition of an anti-hero and his interactions with a certain someone (who I wan't talk about for spoilers) was to empathize that.. remember that the two shared a bond and the "professional asshole" statement was actually the beginning of a rather deep revelation later on..

Rocket is scared, abused and angry.. yet deep down he has heroic tendencies.. dark as they may be.. his rampant dickery is a self-defence mechanism in which he had to be the nastiest in the galaxy to survive - he is likely going to soften and his relationship with Groot and the other Guardians shows he is loyal to those he sees as "family".

Rocket is not evil nor (truly) malicious.. he's got morals, deep under his facade of being the galaxy's most hated.

in Guardians universe that's enough to count because in a world teeming with despots, madmen and completely immoral pirates Rocket is of the "chaotic good" variety, disguised heavily as "chaotic selfish" so he can survive.
