What is that hand sign he is making with his fingers, and pointing at his intended target? Seems like a physical intimidation tactic.

Correct.

Some kind of pagan hand symbol used by punk gang members and similar demon-haunted characters.

Shows they either identify with the Satanic realm or are trying to ward off powerful influences attacking them.

Thanks for explaining it to be, henbane. How awful.
