There are several Gundam series that kill off main characters and don't allow them to come back.

The only exception being Gundam 00, where the mind of one killed Gundam pilot is uploaded into a Quantuum computer and later downloaded into a new "terminal" i.e body. But then that char was never a real Human in the first place.
