Speed Force keeps having headaces due to needing to prevent time paradoxes all over the place. The "future" version needs to be the one that dies in order to appease.... time? Or at least not piss it off quite as much. I think that's about right. It's not so much time, but the time wraiths, of the Speedforce. I don't think they care much about who lives or dies. I just think that the wraiths don't like two of the same people hanging out in the same timeline.

The so-called "rules" of the Speedforce and/or time travel aren't given to us in any helpful detail. But apparently they've been after Zoom for a LONG time. Zoom has been traveling from one Earth to the next, and probably created time remnants often, basically angering the time-wraiths who feel as if he has been "misuing" his time-travelling powers.

When Barry 1 travelled back in time in the S2 finale, that got the attention of the Wraiths, who discovered that Zoom was there. Sure, Barry has already angered the Wraiths twice, causing the death of one of them (thanks to a reformed Hartley). But they probably thought "Well, we got Zoom. We'll give Barry a pass this time."

This website's own page about Hunter Zolomon pretty much says just that, that the wraiths were angry at him for "misuing" his time-travelling powers.
