Evil or not (and he was), the man's influence on popular culture is immeasurable. Therefore,
RIP FF 
Whaat? 
This dude is responsible for several cruel, and I mean really cruel, murderers. Cultural influence is not something that determines whether somebody is FF or not. The comparison may be a little off, but Hitler and Stalin also had cultural influence, yet they were the greatest mass murderers in history.
I never said the murders themselves were justified. (Although it's also important to note that Manson himself never killed anyone.)
Hitler and Stalin hardly ever had cultural influence.
If the murders he ordered were not justified, he just can't be a freedom fighter. He was criminal and modestly successful musician.
Stalin has still cultural influence. Just do a survey in Russia, I bet he gets more approval than Gorbachev. In some communities, there is still a Stalin cult in Russia and the former USSR.
