Why does Vegeta tolerate Android 18? 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.
The primary reason that Vegeta tolerates Android 18 is that he has changed.


He has become more human than a savage who destroyed planets for fun. This change of his is evident and there are many more instances of this in DBS (Dragon Ball Super). For example, in episode 2, he took a day out of his training schedule and went to the amusement park with Bulma and Trunks and the incidents that occur over there also highlight this sea change in his personality. 
In fact, he's in touch with his human emotions, an instance being when
he gets angry over Beerus slapping Bulma when she slaps him for
ruining her birthday party and makes up his mind to fight him whereas
till that point he had been swallowing up his pride and acting like a
clown (episode 7).
It can also be said that he now accepts things as they are. He
realized that he isn't the strongest out there, and has shifted his
focus to becoming the best. He also has realized that there is nothing going to be achieved by revenge, so he doesn't seek revenge anymore.


This explains why Vegeta tolerated Android 18.
