Because it is not necessary. Enough time is given that you don't need to make abrupt manouvers. That is why on an initial RA you have 5 seconds just to start you evasive action at only 1/4 g added or subtracted to your load factor. Abrupt pullups at cruise altitude can be dangerous.
Going against the RA was not rational and a lot of people died because of it.
