There you go. Neither of them is perfect, and neither of them is bad. They have different views on justice. Kayle believes sinners should be purged because she does not believe in redemption. Morgana seems to believe everyone deserves a second chance. Justice is not one dimensional, and both the aspects of it they represent is different, but they complete each other. I don't get why people think Kayle is bad and Morgana perfect. That's not the impression I get when I listen to their VOs.

In addition to what was already posted, I think the poem about Morgana and Kayle points out another flaw.

Toward the city of grand Zeffira, an army of hate descended. The Winged Protectors flew to the people’s aid. Kayle fell upon the screaming host, her blade of fire wet with blood. But Morgana saw what Kayle had not. A secret force within the city! Zeffira’s people cried out for succor, and Morgana swooped down in answer.

Kayle slew her foes in purest wrath. Her body torn and bloody, she cried aloud, “Sister fair, I am sore beset!” Morgana heeded not her cries, her powers bent to shield those within. Zeffira endured, but much was lost, One sister’s love, one sister’s hope. Each saw through a glass, darkly; a failing in the other, a fatal flaw.

I may be wrong, but that feels like heavy symbolism to me. Morgana is too occupied fighting the darkness within, that she doesn't pay attention to the damage that her actions may cause. Meanwhile, since Kayle is blind to that darkness, she thinks directly fighting those who do wrong is the only logical thing to do.

Morgana is Sans, thats her flaw
