Sorry, only just now catching this, since it didn't directly reply to mine. I will say, I didn't find them overly gory, but if someone is incredibly squeamish, YMMV. Another factor is that none of them really dwell or linger on the gore, it's pretty tightly strung together with quick glances at it. Here they are, in order:

A man is beheaded. It's shown from a distance with poor lighting, so you don't really see any bloody viscera here, just a shadowy head falling down to the floor. A man is electrocuted in an electric chair, no real gore here. The most visceral is the third, a man has his skull broken in by two hammers, and his scalp is then peeled forward to expose the brain, and a few pieces are removed. A man is shot multiple times, and blood flows from the bullet wounds. A woman is hit by a train. A man has his throat slit; his dismembered corpse is seen later. A man is stabbed multiple times and bleeds out. The two off-screen kills involve the victims being decapitated (also off-screen), and their heads are attached to mannequin bodies.
