Murderers have an age of consent??? What, I consent to murder someone?
Are you on crack?
There are systems and standards in place for determining what minors will be tried as adults. Your deep-throated advocacy for vicious killers is sickening!
Don't be disingenuous. "Age of consent" is shorthand for the legal distinction between being a minor and being an adult in the eyes of the law. Ask a lawyer what this means if you're still confused.
