"Under a cloud of increasing anti-mutant sentiment, Professor Xavier created a safe haven at his Westchester mansion where he could train young mutants to
use their powers for the betterment of mankind"

The X-men were
explicitly deployed by Professor X as superheroes after he trained them to use their powers, not to hide, but to help and protect people
from evil mutants.
The entire purpose of the school was to teach mutants...to be ethical.
Seriously have you
read X-men?
A telepath sharing their thoughts with someone is them sharing
their own thoughts
From now on just substitute the word "body" for "thoughts"
It is ethical for someone to share access to their body with someone else. It is unethical to share
another persons body with someone else because you do not have the right to decide what they do. Similarly, a person does not have the right to have
access to another persons body whenever they want.
A telepath does not have a right to intrude on the thoughts of someone else without consent just like you do not have the right to access someones body without consent.
It is a very simple concept.
If he's amplifying their own impulses , they're
explicitly enjoying it. They may not be in an uninfluenced frame of mind...but they
are enjoying it.
