Can't speak for either party involved, but perhaps you shouldn't judge if it was inRP or ooRP before you know all circumstances. I myself have often enough rammed my ship into the sun/planet during a fight if death is inevitable or the cargo was too valuable to fall into the hands of your enemies, even at the cost of a transport worth 100 million.
Given that we have plenty of "got away in an escape pod before it was too late", this does not even kill off your character.
This is not bad roleplay just because you did not get your desired blue message with your name at the end of it.
