Rabin assassination

The rabbi once said:
“Rabin’s murder does not seem to me to be more serious than any other murder. On the contrary, here at least there was an idealistic motive at the basis of the murder, and not self-interested as is common in other murders based on the interest of money or power, or based on anger over a romantic background, or because you took a parking space, or any other ‘noble’ motive, or just wickedness for its own sake. Yigal Amir was wrong in my opinion and even committed a serious act, but at least he committed an act that, to the best of his judgment, was noble and for the common good, and of course he was willing to pay the full personal price (after all, it was clear to him that he would not get out of it alive and would not enjoy the fruits of his deed himself). So how is he worse than other murderers?”
Does the rabbi also say this about terrorists?
And if not, what’s the difference? After all, they seem to meet all the criteria in the rabbi’s statement…
