The reason for all the mess in season 2

This guy singlehandedly destroyed Gi-hun's whole plan.

If he could have simply told him about his brother and showed Gi-hun his photo, all this mess could have been avoided.

Bro wants to be a hero but his selfishness costed too many lives.

Also he's the reason Gi-hun's tracker was discovered. He trusted that captain park guy way too much. If only Gi-hun took woo-seok's advice and didn't free him, all this mess could have been avoided and they probably would have discovered the island by now.
