It's hard to say. How many deaths would he cause if he lived? He probably wouldn't directly kill someone, but his actions would have consequences. For example, flying around in a private jet has a very high carbon output. This will result in people's deaths.

It's easier to see the deaths and damage caused by a healthcare CEO, as an example, but this person also causes significant damage. I don't think the other people deserved to die, and the world would probably be better with them, but are their deaths worth it? That's an opinion, and it's very hard to answer. I'd probably say yes, because it likely saves more than eight lives, but we also need to account for the people they would have saved, and the harm it has caused people around them, so idk.
