suicidal

He is an authority on the precursors of suicidal behavior.

After losing his job, his wife, and his leg in a single week, he became suicidal.

Now, that, admittedly, did do an awful lot more damage (the 5th and 6th were almost completely wiped out), but the High Seas Fleet was, in turn, almost completely wiped out (in fact, basically was wiped out, to a man) by the oncoming rest of the British Grand Fleet, and it was decided by everybody that this kind of, like, suicidal, completely suicidal, charge was probably a bit out of character for Hipper, and so we didn't take that particular one into account.

His driving habits are utterly suicidal.
