what type of fallacy is this?

But a man is not animal. He was made in the image of God and he has immortal soul, which means that euthanasia is a pure murder and its supporters do not only reveal their atheism but rather their Satanism.

I think it has circular reasoning, circumstantial ad hominem, and a conclusion that does not follow from the premises

but is that wrong or is there something else i forgot?

I think you are right on.
