50 NL - second nut straight in limped pot, easy call?

[MrSelfDestruct]

Villain1 is running at 20/7/1.5 seems pretty solid but not great.
Villain2 is running at 38/16/5 and is pretty donkish and raises and reraises a lot on the flop.

I checked the flop because of Villain2's aggressive betting.
Cold called the reraise because I want Villain 2 to do something stupid (like move all in). Planned on getting it on a safe turn. The absolute blank hits on the turn and Villain1 massively overbets all in. I snap call.

After looking at the hand at the end of the session I'm quite sure I should have raised the flop...
