i think "rehab" with criminal behavior...
is far more complex than treating
something like addiction.
there's probably no apparent isolated visual cues to follow...
value system must be changed,
and....
one could erase certain memories
if it causes constant trauma - and behavior affected by this.
but overall, not as easy as it sounds....
better to attempt gaining certain abilities/talents
by observing neuro-pathways and changing, that is easier.
