One's man freedom fighter, another man's terrorist. Various Palestinian groups are viewed by the Palestinians as freedom fighters, because they fight against IDF occupation. Same with Irgun, Lehi, even Haganah. Jews saw them as freedom fighters because they fought the British and various Arab forces. Everyone else saw them as terrorists, due to the means they employed during the fighting. Bomb smuggled with the intent of killing British soldiers, and in the prccess taking one's own life, is a clear act of terror. It is suicide bombing. In the end, it is all in the eye of the beholder. Every side in every conflict has it's heroes and terrorists.
