Where you read (or anybody) that Palps is teaching him on THAT way? He is fulfilling a fatherhood to the kid.
Consider that this voice around his ear have been whispering since HIS 9 years to now. Did anyone consider WHAT is the mind of a 9 year old Kid? And what are the consecuences of having a "supreme chancellor" of the gallaxy speaking nice words at you at THAT AGE???? and keeping doing it for 10 years (not to mention that THIS 10 years are chritical on the maturity of a personality)??????
How palpatine is doing this stuff with anakin is clear to me. Anakin don't have the minor chance to know for real that HE IS BEING TRICKED!
