Are you guys forgetting that Boba is eventually named/elected Mandalor? He returns to Mandalor and is accepted by the people as their leader. He then pissed off the Empire enough that they seed the entire planet with a bio-toxin specifically targeting his dna so he van literally never step foot on Mandalor again, then trains Jaina Solo so she can take out her fallen brother who had killed Fett's daughter. I know none of this, or any adult fett stories outside of the original trilogy are canon anymore, but my point is that Boba was accepted by the Mandalorians, so much so that they named him Mandalor and he was a good enough leader that the Empire (Remnant) attempted to assassinate him.
