Both the books and the show make it clear that Wakanda (Black Panther's nation) was
under attack by a hostile tribe. What happened was violent yest, but needed. The Wakandans handled the situation with finality and left one alive so he could spread the word: Leave Wakanda alone. The story contains must political intrigue
and social commentary - that isn't politically correct but historically correct for a work of fiction. The Black Panther is the fist black superhero in all of fiction to be solo and not not connected to an established white character. He is iconic. The animated series' choice to adapt Hudlin' first 6 issues was genius because it's a great jumping on point for anyone who knows nothing about the character and establishes that Storm (yes, of the X-Men) will eventually marry him.
Now about the violence. The young man remarked that in the X-Men cartoons, Wolverine does not kill, however anyone who knows Wolverine from the comic books know that he crosses the line repeatedly. In the cartoon, it was for children and back then you could not show blood in children's programs. Same thing is true for the Batman and Superman series. Batman does not kill either but he toes that line. Remember when he threatened to drawn a suspect in the Gotham Bay while he dangled him by one hand from the Batwing? That was from the animated series' first season. Superman gives it a much wider breadth. The reason why those series worked was that they stayed with source material. The producers for Black Panther are doing the same.
What about the morality of the Panther's actions? I'll table the discussion of Superman, Batman, and Wolverine for later. I don't see a problem with the Panther's actions in the Who is the Black Panther story arc because the Panther is never shown killing anyone. Even in trying to avenge his Father, it's not about murder. Remember killing and murder are not the same thing. The men in the clip below came to steal, kill, and destroy Wakanda. There is nothing in the Bible against self defense. If someone starts a war with you, it's perfectly moral to end it. sometimes that mean ending them. I want to end with a quote from Ecclesiastes 3:1-8
1 There is a time for everything,
and a season for every activity under heaven:
2 a time to be born and a time to die,
a time to plant and a time to uproot,
3 a time to kill and a time to heal,
a time to tear down and a time to build,
4 a time to weep and a time to laugh,
a time to mourn and a time to dance,
5 a time to scatter stones and a time to gather them,
a time to embrace and a time to refrain,
6 a time to search and a time to give up,
a time to keep and a time to throw away,
7 a time to tear and a time to mend,
a time to be silent and a time to speak,
8 a time to love and a time to hate,
a time for war and a time for peace.
