Maul? Because Maul just killed his master and he was a Sith, Sith deserve to be captured if they can be safely disarmed of if they already are by luck or whatever. However if a Sith fights you, a Jedi is within its rights even within the code of the Jedi Order to strike down the Sith.
and did you even see ROTS? Anakin killed Dooku because of the Dark Side, Because Palpatine made him do it.
