We hear this a lot, but I am pretty sure CIG is on record that UEE ships do not have a self-destruct, only Vanduul ships. Also, there is a plan to hugely inconvenience players when they die--no details forthcoming yet, but this is intended to thwart the kind of solution you're proposing.
Besides, if it's okay to blow up the ship with you aboard thus killing them, isn't it okay to put a bullet into their brain pan and leave your ship and person in place? The point is, there are conditions one can kill in almost every ethical theory. The only exceptions I am aware of are ancient Zoroastrianism, which so far as I'm aware is quite dead, and more modern Christian pacifism, which most admit is based upon a misunderstanding of Jesus' teaching. So if most of us believe you can kill under certain circumstances, like self-preservation, why would not your avatar do similarly?
Kill 'em all and let God sort 'em out!
