Never let anyone else define you. Don't be a jerk just to be a jerk, but if you are expressing your true inner feelings and beliefs, or at least trying to express that inner child, and everyone gets pissed off about it, never NEVER apologize for it. Let them think what they want, let them define you in their narrow little minds while they suppress every last piece of them just to keep a friend that never liked them for themselves in the first place.
Current Krillin really shouldn't be even remotely close to Freeza-level, tbh. That said, if this fight happened in DBS, I could still see Krillin winning... Toriyama's always had a hard-on for him.
