'Course, what did Luke know, he was only there.
Not according to the WTBTS . They state that Luke was not an apostle but a later convert of the apostle Paul .He compiled the Gospel of Luke by interviewing people involved in the story . I think it possible that Judas was there for the passover celebration but left before the bread and wine of the new covenant got to him at the table.
I still believe the great crowd inherit the kingdom of the heavens for the millenial reign of christ . The 144k are martyrs that comprise the first resurrection .
