I have to agree with Nick. If you look at accidents here over the past years, engine failures in twins are not killing people. Flying into the water, into rigs, into thunderstorms, etc are killing people. Mechanical failures of other components are killing people, and merely frightening others, because of the skill of some pilots. I'd far prefer an engine failure to a tail rotor failure.
I don't spend much time worrying about an engine failure, if any, except on checkrides when I know it's going to happen. A simple engine failure enroute is an annoyance, nothing more. On takeoff it can be critical, but it seldom happens there, despite what anyone may want to believe. Look at all the reports you want, and you will find very few in which an engine failed on takeoff. There have been none at all that I know of in which the result was the tail hitting the heliport. Focusing on engine failure to the exclusion of all else, especially to the exclusion of CFIT, is incredibly short-sighted.
And now back to your regularly scheduled hand-wringing.
