Things to consider:

• What is the nature of the threat that could move your character to betray those they love? Is it personal, or would it be detrimental to a group or society as a whole?
• Would your character experience guilt or remorse in betraying those closest to them?
• Does your character harbor any significant attachments to people in the first place? Do they prioritize themselves or anything else over their peers?
