Regarding victim number one. Bringing a gun to a protest and starting shit then shooting people doesn't constitute self defense because you normally can't provoke the situation you are defending yourself from. Also the only thing that made the situation deadly dangerous was literally the gun in his hand if not for that it would have been a fist fight at worst. More likely absent a weapon to give him courage he just wouldn't have started shit.

Regarding victims 2 and 3 they were trying to stop what they correctly perceived as an active shooter they did not pursue lethal force against him he could have surrendered the gun non-violently. You normally have a legal obligation to use the lease force possible.

The law being what it is guilt or innocence it a fight is often questionable and subject to state specific laws but morally speaking I don't understand why anyone would not hold him responsible for what happened. He is by all accounts a garbage human being and people are dead because he is a garbage human being.

Here is what one of the people who helped him win his legal case said

We invested significant effort to craft the image you witnessed during the trial. We outfitted him in new suits, arranged for his haircut every weekend during the trial, and dedicated over 200 hours to prepare him for direct and cross-examination. We employed the world's leading jury consultant and conducted extensive research through three mock trials to identify the ideal jurors and the most effective approach for his testimony.

Transforming a middle school dropout who was "angry at the world" with a history of violence and an unhealthy obsession with guns and killing into a respectable young man with a desire for higher education and a promising future was no easy feat.

It was a meticulously crafted facade, which we sincerely hoped he would grow into. Instead, he squandered a full scholarship to study any subject at any university in the country to become a divisive douchebag and antagonize black Americans on college campuses. Kyle failed to learn a single thing. He remains the same uneducated, arrogant, and antagonistic individual, incapable of telling the truth.

Now, he genuinely believes he is the show pony we created and has surrounded himself with sycophants who fuel his inflated ego because they prioritize their political agenda and Christian Nationalist worldview over his well-being.

Despite my efforts to guide him toward a better path in life, the allure of notoriety triumphed over the prospect of putting in the hard work of pursuing an education. I regret my role in shaping him into whatever he has become. If I had known what I know now about Kyle's History, I wouldn't have been involved.

He's also a moron. He obtained his high school diploma by cheating on online tests and then went to take the ASVAB and managed to score a 10, a typical average score for a high school graduate is 50, the minimum you can get into the military is 30. We are talking about questions like

If there are three quarts of gas in a gallon container, how full is the container? 50% 60% 75% 80%

I don't even know how its possible to score a 10
