As above, having two engines just means you’re twice as likely to have an engine failure.
And then the consequences of mishandling it can be (and often are) far more severe than they are in a single.
Granted this can be largely mitigated by good training, experience, and recency.
An engine failure in a bizjet is almost a non event. The performance margins are such that you’d have to be trying very hard to bugger it up after a failure. Apart from standing on the correct rudder pedal (and even that you don’t have to do in the latest version) there’s virtually nothing else to do except fly it.
Different story in a prop aircraft where the margins are much smaller and you have (potentially) the drag of a windmilling prop to deal with as well.
All I have done here is point out the fact that the accident stats are clear when it comes to single engine turboprops.
It is a myth that twins are safer. Sure they probably
should be safer, but for some reason they aren’t.
