Charles Manson has made a couple of admissions of guilt. I'm not a lawyer but this is what it sounds like when he says perhaps he should've killed more people. I'm paraphrasing here, but that is pretty close, and perhaps the closes, he's come to taking responsibility for the brutal Manson Family murders of 1969 of people the Manson Family didn't know or had ever heard of. The interviewer asked a basic straightforward question and got a fairly straight answer from Charlie.
I believe a borderline silly question has to be asked of Charlie Manson: Do you feel responsibility or remorse for the murders? It is a silly question because you know what he's going to say: Remorse for what, what murders, what about everything you've done to me and so forth. It has to be asked because he's the one man who knows exactly how many people he's responsible for killing and you are looking for new information here and, if nothing else, to get a new reaction out of him.
This is not much of an interview but certainly entertaining. The interviewer is not asking many questions but really just letting Charlie do his shtick, his routine, and letting him go off on the world and what he thinks of things and letting him speak and make up for lost time spending so much of his time not just in State prison but in solitary confinement, during which the world that is still fascinated by the man gets to see how he is doing and what he is thinking.
