If that same male was not eaten, but went on to impregnate more females, then shouldn't that trait be favored over being eaten?

Provides sustinance for the female who in turn will be able to lay more eggs/have more eggs survive.

Which is why in some species females will drain the wallets of the males

In most cases the female tries to eat the male from the beginning. It has nothing to do with the act of sex. There's plenty of evolutionary advantage in being an all around territorial cannibal.

As a male, I prefer to be the one doing the eating.

what's the evolutionary advantage of being a furry?
none. just an unintended (not that a natural process can actually
intend' something) consequence of some thoughts from a brain capable enough even though it was designed for other reasons.
In the same way, spiders just happen to develop to really being into vore.

The spider eating the male doesn't decrease the number of viable offspring, because the male can only get laid once in most cases (they don't keep making sperm).
So there is no reason why tendency toward such an activity should be eliminated by by natural selection.
Now, if males evolved to be able to impregnate many females, then it probably would be eliminated by natural selection. But you can't ask why they have not evolved in such a manner yet, as evolution is an entirely blind naturalistic process.
It doesn't TRY to make the perfect organism.

For the woman, it's more perfect to get rid of their mates. Many women would love to have that instinct. Many already do.

In the wild, the chances of mating are actually fairly slim for males. Many males never even SEE a female, let alone get a chance to score. As has been said, the females are only in it for a meal, but they allow the males to mate with them because it saves them a risky fight to the death. Because the male is able to do as he pleases until he dies, he is actually able to get MORE sperm into the female compared to other non-cannibalistic species where the female tires of it before he is done. The extra meal helps the female develop the young, as also said.
This phenomenon is surprisingly common among insects. Black widows and praying mantises are just the most famous.
