Part of being an adult is having the freedom and autonomy to make mistakes on your own.
There's a mindset these days - and I'm not pointing the finger here, I'm saying this in a very broad sense that encompasses the polical arena, national affairs, etc. - that people need to be supervised for their own safety. It's essentially a smokescreen for privacy violations, exploitation and loss of freedom.
"Dangerous" magic tends to be coercive magic, in most cases. In the wrong hands, it tends to do nothing. In some cases it does seem to backfire.
When I was five, my parents allowed me to bloody my knees learning to ride a bike. They were correct in doing this, I think, even though I was very young. I would certainly never deny an adult that level of autonomy.
Maybe it's my DNA (four Revolutionary War soldiers, etc.) but I tend to be very leery of controlling behaviors. If someone asks me what I think of something on an ethical level, I might sermonize, but if they ask for simple information, I provide it. It's their call what they do with it.
