As a creative work, Oleg and team should be give their artistic licence to interpret death in any way they see fit.
As the developers of damn fine simulations, I sure Oleg and Co would accept any concrete data that anyone can supply that proves their interpretation wrong. They've done it in the past and I'm sure that they would do it in the future. But they are fairly particular about their sources, No hearsay or second hand information.
Any voluneers to gather some objective, first hand data??????
