A guy is condemned to death. He has to choose a room. Room #1: A fiery inferno. Room #2: 50 Assassins with loaded guns. Room #3: A room full of hungry lions that didn't eat in 3 months. Which room is the safest?
The safest room might be the one he is in right now. But if he has to choose between those three, room #3 seems to be the safest of them. If the lions didn't eat in three months, they are most probably long dead (although the stench must be pretty horrible).
Assuming there's somehow still alive, how difficult would it be to fight them?
