I think that's an exception. You passed an off-color nonsplashable bomb for an on-color bomb. Regardless of rarity, a 4/4 flying vigilance for 5 mana just wins games and is a must-answer. If I'm white, pretty sure P3P1 I just snap-take Serra over almost any card other than some nutty on-color Mythic.
It's different than passing an off-color bomb with money for an above-average common.
The problem with hate drafting is that you may not even play against that person
You take the bomb not to hatedraft but because of the EV. The value you get from taking the money card now is better than the %win increase (and increased chance at prize) you get from taking some premium common. Unless this is top 8 draft of a big tournament, take the money now. The prize isn't worth it.
