Hi Tim,

I don't know if the antichrist will realize he is the antichrist. Satan uses deception as a weapon to accomplish his purposes. A person in deception is usually blinded to the truth by choices they have made. All of life is about making  the right choice.
Adam and Eve were confronted by Satan and made a choice. They made a bad choice and so will the antichrist. Believing that which is contrary to the word of God brings consequences and regret. Here is a scripture about temptation.

1Co 10:13 -There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it.

About deception

Mt 24:4 - And Jesus answered and said unto them, Take heed that no man deceive you.

Mt 24:5 For many shall come in my name, saying, I am Christ; and shall deceive many.

Mt 24:11 -And many false prophets shall rise, and shall deceive many.

Mt 24:24 - For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.

Mr 13:5 - And Jesus answering them began to say, Take heed lest any man deceive you:

Mr 13:6 - For many shall come in my name, saying, I am Christ; and shall deceive many.

Ignoring God's word gets us in trouble and gives Satan a legal right to attack us. Keep your guard up and your full armor of God on. Jas 4:7 - Submit yourselves therefore to God. Resist the devil, and he will flee from you.

The antichrist knows the word of God and chooses to ignore it.

Yours in Christ,
