faithlessly

In betraying fashion

Faithlessly describes acting without loyalty, allegiance, or commitment to someone or something.

A spouse who faithlessly abandons their marriage vows breaks a sacred promise; an employee who faithlessly shares company secrets betrays their employer's trust.

The word carries strong moral judgment, suggesting not just absence of faith but active betrayal of it.
