Please try to relax.

You want to put a point value on the lives of the people killed in NY?

He got the max according to the law of the government in the nation where he was arrested. The max is the best they can do.

After he serves his sentence, perhaps he can be extradited to face civil charges in the US. He won't be in prison, but he won't have two coins to rub together for the rest of his life.

Prison is not fun. Especially not for someone convicted of a heinous crime. Convicts, too, have a sense of justice.

The only thing that bothers me about the length of his sentence is that he'll only be in his early 40s when he gets out. I'd prefer he were a tottering ancient without the energy to pick up where he's left off, if he is still so inclined.
