oh and yeah the Dark Side doesn't get enough credit in Anakin's Downfall because the Dark Side is like a drug..addicting..and confusing
When Anakin killed the Tusken Raiders it was like... he got a lil sip of Dark Side...and thats where the addiction began
when he killed Dooku again. the darkside was there and he could feel it... and he wanted to feel the DarKside again. And palps encourgaging him only made things worse..then when he kills Mace Anakin looks really drugged up...that is when the Dark side has completely blinded and taken over him he is no longer rationaly. He let the addiction take over him...and not until episode 6 is he able to get away from this powerful addiction...which we really have no idea how it feels since we are not force users and stuff
