RIP. A great man who fought an evil cause. And in so doing employed violence and gathered what allies he could. Fighting evil leads to many grey areas, since, when is violence ever "good"? But if the end result of violence leads to a greater good, isn't it for the best then? Big questions.
And a big impact. Ask yourself if you'd be prepared to give up most of your life in the name of a cause, and then have your actions inspire billions? Only a few get asked, and even fewer can eventually say yes.
