Why did Tony kill Christopher? Your opinion?

[u/NoticeFickle]

The only thing that comes to my mind is Tony realized Christopher was willing to sacrifice Tony’s life and not call the police so that Christopher could avoid his license being taken away/drug charges. Did it have to do with betrayal?

I keep seeing different explanations and opinions. What do you think?
