I never understood this whole "wild or gambling thing". Wild seems to refer only to overbids, can severe underbids never be wild? And every action is gambling. I really think it should be more like "highly against the odds" or "highly unusual for the class of player involved" or something.
Take south's action. I don't think "wild" is the right word. Is it gambling? Sure, just like any action would be. But I know it's strange, it's terrible bridge, and that even if east had north's ace AND king of clubs he would be making 3♥. South's action is highly against the odds, highly unusual, and I won't let him take it back.
Yes if north has 5 hearts then not doubling will be bad.
There are several things that W could have been thinking about. If he is thinking about a raise, then clearly you want to double almost all the time, although even so partner might have a 4333 hand which won't play well.
If he's not thinking about raising (he's just short of bidding a suit himself or a 2N enquiry) then it could easily be disastrous to bid. As an extreme example, you could be moving 2S minus some to 3 of a suit tick. Give partner say QJ97xx, void, xxx, xxxx and W an 0643 14-15 count for example.
I don't think passing is wild and gambling.
