I would rather suffer the end of Romulus a thousand times. I would rather die in agony, than accept assistance from you.
Note: Nero's ship was being destroyed by a black hole, and Kirk offered him a chance to evacuate. Nero adamantly refused, and Kirk ordered the Enterprise to open fire, accelerating the destruction of Nero's ship and killing him. Nero was from the future, where the Starfleet Enterprise had offered assistance in saving his planet from destruction via a black hole, but they failed, which is what drove him to come back in time motivated by revenge, and why he decided he would rather die than accept assistance from them.
