I don’t know that I’d say that any more than characters like Captain America, who’ve also died multiple times. (Or Jean Grey—but no need to go there again!) The one thing Wonder Man has in his history that makes what you’re saying maybe a bit more applicable than others is that he died in his very first story, and then came back resurrected years later. In that way, he is closer to Jean Grey, whose origin as the Phoenix was that she died and then re-created herself, in essence.
Yeah, but Wonder Man has been established as a being made of ionic energy, and energy never dies - which was a central part of his 90’s series. So we all know he’ll eventually manage to gather all the pieces of him together, or someone else will make the process quicker and bring him back to life, like Wanda in Avengers Vol.3.
Things get awkward with Beast and Wonder Man when they point each other out about their own mistakes and hypocrisy.

I have determined what to do about the love (the answer is “reblog old posts i tagged him in)
What If Wonder Man had not died? (1989)
Apparently, Captain America wouldn’t stand a chance of being the object of Wanda’s fangirling, and seeing his sister’s attentions returned would make Pietro even more of a jerk than usual.
