Who are the devil’s angels? (Mat.25:41; Rev 12:9)

Jesus has already used similar language in saying that the Pharisees are children of their father the devil (John 8:44)

Matt.25:41 is partly just apocalyptic language (no different from Rev.12:9) but there may be a literal edge to it as well, and the “angels” in this case are the same as the “goats”. Of course the “goats” are not really goats, and not really angels, they are men and women.
