Anakin did become evil, so Obi-Wan was justified doing all that.
He became evil because he was Forced...(get it..Forced..)
All because of a parasitic infection.
Wouldn't have happened if he was vaccinated.
I wish I could join PETA in animal activism, but many times they go too far and do something incredibly stupid.PETA offers ample entertainment at their splendid "Sea Kitten" site:

With massive amounts of sadness and despair I regret I am forced to report that the Sea Kitten stories and Create Your own Sea Kitten sections have expired or, perhaps, those evil vile dangerous deadly yellow running-dog imperialist capital roadist filth have infiltrated and removed those valuable pasts of the Sea Kitten site. Hopefully they will return in the future.
