Yes, Mandalore is tough. He is nasty in both the good and the bad sense. However, for me the bad heavily outweighs the coolness factor, since it disgusts me how he takes pride in attacking the innocent and helpless of the Republic. That's the infantile boy who torments his baby sister and makes her cry because he doesn't feel he gets enough attention from his mother. That's how I see the Mandalorians. I can appreciate their skill in war, but their attitude is immoral, inexcusable and infantile.
Mandalorians are somewhat referenced as Spartans, pure warriors, that don't fear nothing.... I personally think that they are just all-out tough, that's it, but attacking the innocent and stuff like that, is a bit disturbing.
