Can I divorce my wife for threat to life?

Yes. It's a behaviour for which you cannot reasonably be expected to live with your wife. Section 15 (2) (C) of the Matrimonial Causes Act.

Yes. If your wife threatens your life, it can be a ground to file for divorce. Section 15 of the Matrimonial Causes Act outlines several grounds upon which a person can bring a petition for dissolution of marriage, one of which is that the Respondent (your wife in this case) has conducted herself in the manner that you are not reasonably expected to continue to live with her. If she is threatening your life, then she is conducting herself in a manner that you are not reasonably expected to continue to live with her. Thank you. Ndubuisi Nwegwa, Esq.
