And you discount the obvious separation of Christ's brothers and the Apostles, as differentiated in the text?
That's quite delusory...
John 2:12 after this he went down to Capernaum, he, and his mother, and his brethren, and his disciples: and they continued there not many days.
John 7:3 His brethren therefore said unto him, Depart hence, and go into Judaea, that thy disciples also may see the works that thou doest.
John 7:5 For neither did his brethren believe in him.
John 7:10 But when his brethren were gone up, then went he also up unto the feast, not openly, but as it were in secret.
John 7, 2-5:
But when the Jewish Festival of Tabernacles was near, Jesus’ brothers said to him, “Leave Galilee and go to Judea, so that your disciples there may see the works you do. No one who wants to become a public figure acts in secret. Since you are doing these things, show yourself to the world.” For even his own brothers did not believe in him.
Just based on the first verse I could see where the “brothers” were some of his twelve disciples, and the “disciples” are the crowds of followers of Christ. But then that would not make sense with the last verse. And recall that in Nazareth most of the folks didn’t believe he was Christ, presumably some of His own family.
It almost seems like the “brothers” were baiting Jesus. And they also were mistaken in him wanting to be a “public figure” - presumably to be the leader of a revolt against the Romans.
As I posted way back, it seems that lying for a strategic/tactical reason against the enemy is not a sin. Just like others have posted, killing an enemy in battle or in self defense is not a sin.
