It’s from Full Metal Alchemist. His name is Shou Tucker.

Doesn’t hit as well without the full episode context:

A man so caught up in scientific inquiry and progress that he cares not for the people in his life, who he's obligated to protect. He fuses his daughter with his dog, proclaiming his great achievement while the new chimera begs for death to be put out of its misery.

The show explores subverting rules of the universe, life and death to a degree.

Trust me, if you really don't know, it's best to keep not knowing. The worst of the bunch, no doubt.

The worst one up there. Yes, worse than the dude who eats his kid.

He's a bad bad man, also known as The Sewing-Life Alchemist.

Its from Full Metal Alchemist. Dude fuses his daughter with her pet dog... I'll just stop there.

shal tucker from full metal alchemist, at least the first series. he used his daughter to create a chimaera with thier doggo, in attempt to perform human transmuation because he was afraid of losing funding from the government, he was able to show him that they can talk so he kept his funding. i think the chimaera was in constant agony, so one of the other antagonist scar mercy killed the chimaera.
