The high priest then asked Jesus of His disciples, and of His doctrine. Jesus answered him,
“I spake openly to the world; I ever taught in the synagogue, and in the temple, whither the Jews always resort; and in secret have I said nothing. Why askest thou Me? Ask them which heard Me, what I have said unto them: behold, they know what I said.”
And when He had thus spoken, one of the officers which stood by struck Jesus with the palm of his hand, saying, “Answerest Thou the high priest so?” Jesus answered him,
“If I have spoken evil, bear witness of the evil: but if well, why smitest thou Me?”
Now Annas had sent him bound unto Caiaphas the high priest.                        John 18:19-24

Just because the officers did not know whom they were striking does not mean they are without charges themselves. They had just struck the face of the Creator of all that is (Genesis 1; John 1:1-3; Colossians 1:16-17). They thought they were doing God service by protecting the honor of a high priest who knew who He is (John 11:49-52).

Jesus, of course, spoke no evil. He simply gave an answer that should have been known. It was the blindness, and the darkness of evil that was working in the heart of the high priest Caiaphas that was the real issue. Willful ignorance, especially, is not bliss when it comes to knowing who Jesus is.

If you have came to this site, and have taken the time to read any of the information posted here on Jesus Christ I pray that you will hear the Holy Spirit of the Lord speaking to your heart and mind, and that you will have your eyes opened to the truth of who Jesus is – the Christ, Son of the Living God. He died for our sins, was buried and He rose again; and He is coming again. Repent, believe and receive Him.
