I think that banishing Cole is a good idea cause Cole can think about what he has done an the island and he was alone so no one can bother him and it will be better cause no one can get hurt like Peter he keeps on getting nightmares about Cole so banishing Cole is a good idea  so Peter  can stop getting nightmares about him the seconded thing that’s  good getting Cole banished is him learning about how to survive in the wild and can also control his temper and learn how to control it and think positive 

 WARNING WARNING THIS IS A SPOILER CONTINUE IF YOU WANT A 

SPOILER

He survived on the island but also had a bad temper like when he fought the spirit bear he said “I’LL KILL YOU” but he lost the fight when he fought the spirit bear and now he is laying on the floor and doing nothing

i also think that the circle should banish Cole cause he can prove one more time that he can be trusted
