Because I don't need some man to tell me what's right and what's wrong.

Especially not some ancient out-of-date sociopath from the 1960s, with a ponytail but without a conscience.

If his teachings are so good and true, why do people have such vastly different interpretations of the meaning?

According to his own words, the only difference between himself and a murderer is a mere difference in taste or personal preference.  He likes blue, murderers happen to like red instead.  He does whatever he wants to do, and so do murderers.  He's admitting that he lives by the same rules that murderers live by.

Murderers just have wrong thoughts, but he is pure and perfect.
That's why he's never murdered anyone - because he doesn't want to.
What if he did want to kill someone?
His solution for immoral behavior seems to be "never have any immoral desires". 
Since he can't back that up logically, you'll have to abbreviate it to "anything you want to do is good."

And for some reason you actually still follow and preach these long-abandoned ideas -
ideas that were only popular with narcissists and spoiled white kids 50 years ago in the tie-dye age,
with the highest concentration seen among homeless STD-ridden drug addicts.
Their ambition in life was to avoid work and avoid soap,
but some of them are still on TV being worshiped.  Sad.
