Probably a stupid question but...
I was watching Resurrection 'F' and when 18 appeared on screen this question popped into my head. During the Android saga he was pretty much curb stomped by 18 right? (Memories are a little clouded) And Vegeta being as prideful as he is would he really let 18 live regardless of how "good" he became?
Is it just a plot point that wasn't explored? Is Vegeta's switch to the good side cause for this? I just find this one a little hard to believe. I'd probably believe it more that since 18 is important to Krillin and he is important to Goku, that Goku had something to do with it.
Again, sorry if this question is dumb.
