By the time you are given a command you should have flown enough, thought enough and listened to other captains in the bar enough to have some idea of what you are going to do in a catastrophic situation. You'll still get some things wrong.
A colleague had an uncontained #2 failure in a trijet and abandoned after V1. They were light on a long runway. The aircraft had lost three of its four hydraulic systems.
N.B. I am NOT recommending stopping after V1.
