[Harry Potter] I am Lord Voldemort. I control the Ministry, including its supply of Time Turners. Should I issue one to each one of my Death Eaters, to use to reverse time in case I am killed in action?

Time turners are obviously very dangerous, and I wouldn't want my followers using them while I am still alive, lest they unintentionally erase me from the timeline, but if I am killed, what do I have to lose? I could always cast a spell upon them that stops them from working while I am still alive.

The Ministry should have tons of them, for Merlin's sake, they issue them to 13-year old girls who struggle with class workloads, they can't be that rare! Muggle schools don't issue Ferraris to students who struggle with getting to school on time, and if I really wanted every one of my followers to have a Ferrari, I could still easily do that! 

Even given my large amount of Horcruxes, regenerating a body is hard! It's so much easier to send someone back in time than to send an imposter to rig a months-long international wizarding sports competition to get some enemy blood again!

In the HP universe, time is fixed in the sense that the modifications done due to time travel have always happened- there is no changing established events since time travel becomes part of established events. 


So if Voldemort dies, he dies, end of story- time travel is not going to change that. Any attempts to do so have already been attempted and failed.
