Should governments kill people? Should the military or judicial system (death penalty) murder people?

NEVER, unless it's necessary for self-defense or defense of others.

Politicians go with what they think the majority wants.

There are people who are just to Dan evil to be here

Only if they want to be dead too. The public has the right to defend its self in that case.

If the Supreme Court votes yes on the death penalty. It certainly shouldn't be up one person, especially William Barr.

The death penalty should be banned in all 55 states and territories plus DC, and it should be banned at the federal level and from the military code of justice. The death penalty is expensive (much more expensive than lifelong incarceration), it is barbaric, it is sinful, and it leaves the possibility of injustice. How many people have we seen released from death row because their convictions were later vacated (a.k.a. turns out they didn't do it)? Imagine if those inmates had been executed before it was found out that they were innocent. The government would have just executed innocent people. You can release a wrongfully-convicted prisoner, but you can't un-execute someone.

Only enemies during war as a result of battle. Killing via judicial proceedings is vengeance not justice.

It is how the Clintons did it

only when absolutely necessary
