To be honest, this is a videogame and a violent one at that. Getting exploded is getting exploded, can't be particularly sensitive to how it happens one way or the other.
My biggest concern with such a thing is that it easily boils down to griefing.
Logging out for the night? Just wanna pop in for 30 minutes to be a prat? Load up the suicide ship, fly up to player Y and explode yourself.
