Can vulture's eat someing alive if they have no other chose?

Vultures rarely hunt down healthy animals,but occasianolly they kill very weak or sick animals,also fatally injured ones,this may happen.

Keep in mind:vultures rarely run out off carion because

if an animal is physically healthy to die of weakness,it may be weak enough for a predator and vultures are patient letting predators eat first,then they eat left overs of the carcass.Vultures are also agressive birds and the hungrier the vulture,the more agressive the bird is.
