Mandalorians around the galaxy are well known as 'Jedi-Killers'.. Many Mandalorians have slaughtered Jedi and many Jedi have killed Mandalorians. I'd say they are probably evenly matched, even Darth Vader had a respect for Boba
Mandalorians aren't jedi killers. Theres only a few that actually hold that title as being such, and even moreso that have actual evidence of killing jedi some just have the title just because, even moreso its actually even harder to pin down who is a jedi killer or not because even some of the evidence is complete ********.
