Final answer:
Kappa Sigma removes brothers for violations of their code of conduct after an investigation and fair hearing process.
Step-by-step explanation:
Kappa Sigma, like many Greek letter organizations, has a set of rules and standards which members are expected to follow, commonly known as a "code of conduct." When a brother acts in a way that is counter to these established guidelines, it may indeed lead to disciplinary actions, which can include removal from the fraternity. Each chapter of Kappa Sigma may enforce these rules slightly differently, but the general process involves an investigation and a fair hearing before any violation can lead to expulsion. Members must uphold the fraternity's values and ethics; failure to do so jeopardizes their membership.
