I really dislike questions like yours, where you 'correct' Jesus because you know He didn't mean what He said.
44 “They also will answer, ‘Lord, when did we see you hungry or thirsty or a stranger or needing clothes or sick or in prison, and did not help you?’
45 “He will reply, ‘Truly I tell you, whatever you did not do for one of the least of these, you did not do for me.’
46 “Then they will go away to eternal punishment, but the righteous to eternal life.”
Jesus is even more merciful than you want but you don't take Him seriously.
