But he's just a timeline remnant; even if a version of him from the future is destroyed, the fact that his origins take place in the future, he can't be killed in the past for good. Nah, this one is no longer a time remnant ever since he and Barry rewrote reality: Wellsobard is the remnant now.

Current Thawne is what was described in the comics as a "living paradox": he wasn't supposed to exist, but does, because his "nonexistence" happened to a different version of him. The rest of the Thawne Family is gone now, though, which is what Eobard is probably trying to remedy with the Spear of Destiny.
