What would you consider to be the ultimate betrayal? Could you forgive? Let me give you an example of what I would control to be the ultimate betrayal. You go over to your sibling house. They ask you hold a bag for them. Your sibling know that the cops are after him/her, so they ask you carry it out the partment. The bag has drugs in it. Your caught and you explain to them what happens. They don't believe you, and you ask your sibling to corroborate the story. They won't do it. So your sibling allows you to rot in jail for them. This is a true story too. It happened to somebody I knew.
