SUICIDE?? Look at the site [GOOGLE]for Egypt AIr Flt 667 . That fire in the CP's O2 line at altitude would have been non recoverable . The AC would have continued to fly . Look at the damage to the controls . IFF/SIF burnt UHF/VFH burn. Flight deck destroyed from the CP position . Pressurization gone in moments temps freeze in moments . I am an American, A Big Boeing fan. Boeing issued a fix for this fault on the 777.
