Sacrificing

[IntoFire]

Does using {Sadistic Hypnotist}'s ability count as the death of a creature?  And would this affect morbid?

[Deathstorm]

Yes it does

Dies means goes from the battlefield to the graveyard. Doesn't matter how or why this happens.

[ibtrickey]

Yes and yes:)

700.4.: The term dies means "is put into a graveyard from the battlefield."

Also, dying is different than being "milled" ,by say {millstone}, because they are sent straight from library to grave yard. Sacrificing does send them from battlefield to grave, so it counts
