ITS NOT THE JEDI WAY!
Anakin severs Mace's lightsaber arm upholding the Jedi code and his duties of Chancellor's Bodyguard and Defender of the Republic.
Yeah.. Um Mace.. we are going to need the Jedi membership card back..
It seems Mace is driven to the darkside by his vendetta to rid the Sith from the Galaxy.. Mace's vaapad style of fighting seems to be the most effective when the line between light and dark is crossed..
Anakin performs his duty to the Republic and Jedi Code.. the line between light and dark blurs.. Same old Anakin...different Mace and Jedi..
Did Sidious see Mace's vulnerabilities...as well as he could Anakin's//
