Kruldar,
Why else do you kill somebody?
Other than cos they hold an opinion which is so different from yours that it threatens you?
Oh, some kill for pure pleasure, I spose. Some kill for money. Some for revenge. Some to protect their friends, some cos their guild/city/order asks them to.
But when someone holds an opinion, they are free to, without danger of being attacked, UNLESS they advertise to the world that opinion. Dont try to say that Lemon was merely warning people of Spawns coming, she longs for it, and urges others to do the same. To Israfel, Spawn is evil, and by association, so is Lemon.
Whether he is right or wrong in his assessment is not the point. He may be lying about his reasons exactly as you say, but by his words and actions you cannot prove him a liar, so quit the defamation, it's childish. You didnt see Saruman going all out to defame Israfel, why cant you follow suit?

P.S. *scratches his head and wonders why he is defending Israfel so much these days, then sighs*
