Running for office wouldn’t have stopped the CEO

You’re right, and neither does this extrajudicial killing. Nothing changed in insurance policie, and nothing will likely change. But running for office has a much better chance of helping people in the future than murdering a CEO.

And yeah, insurance companies spend billions lobbying government, and that’s why running for office yourself is valuable, you can refuse to accept these donations. You need to find your own powerful group to get you elected (maybe labor unions?), because that’s how the game is played, but there are options if you’re laser focused on one type of policy.

however just

Justice is the lawful administration of law, and extrajudicial killing is, by definition, unjust. Depending on your moral code, I also argue it’s immoral, because it’s only moral to kill to protect innocent lives, and retribution isn’t protection.

If killing this person was likely to actually change company policy, I could see it as moral, but there’s absolutely no way a reasonable person would think that. This was a crime of passion, not of justice.

Killing a CEO certainly doesn’t solve anything…
