I would say yes but the difficulty comes with making that judgement and accepting it. Pinning AntiChrist on someone is hard when everyone who goes against Christ, even in small ways is a little antichrist:
1 John 2:18
[ Warning against Antichrists ] Children, it is the last hour; and as you have heard that antichrist is coming, so now many antichrists have come; therefore we know that it is the last hour.
1 John 2:22
Who is the liar but he who denies that Jesus is the Christ? This is the antichrist, he who denies the Father and the Son.
1 John 4:3
and every spirit which does not confess Jesus is not of God. This is the spirit of antichrist, of which you heard that it was coming, and now it is in the world already.
2 John 1:7
For many deceivers have gone out into the world, men who will not acknowledge the coming of Jesus Christ in the flesh; such a one is the deceiver and the antichrist.
