A statement from the Justice Ministry said: “The court has found that at the time he committed the offense, the accused was not psychotic, fully understood the facts, was responsible for his actions, had no difficulty in understanding reality and had the capacity to prevent the crime.”
He is due to be sentenced next month.
The murdered teen’s father, Hussein Abu Khdeir, had called for the demolition of Ben-David’s home, in keeping with the destruction of homes of Palestinian attackers.
“His house should be demolished just like they do for all other terrorists,” Mr Abu Khdeir said outside the courtroom.
The murdered teenager was honoured on Israel’s terror victims’ memorial this week to mark Yom Hazikaron. He is believed to be the first Arab killed by Jews to be added to the memorial.
