Given a fentanyl related death & murder charge: https://abcnews.go.com/US/suspect-arrested-connection-deaths-2-men-drugged-beaten/story?id=98308800
Given that the suspect had beaten and robbed the victims, I would think it reasonable that the courts would "throw the book" at the suspect, when he is found guilty.
If on the other, hand he was a friendly (no beating, robbery & not a drug dealer) and the suspect merely gifted deadly narcotics to the victims, would the courts view this scenario no differently? Or would the suspect receive lesser charges / sentences if found guilty?
To facilitate the question, please assume any applicable NY / NYC / Federal statute.
