Because if we assign derived class in to base class pointer then if we call delete then only base class destructor will call, base class destructor will not call.
So object will not fully destroy. And now if the destructor of base class is virtual then derived class destructor will call and object will fully destroy.
So object will not fully destroy. And now if the destructor of base class is virtual then derived class destructor will call and object will fully destroy.

Because the initialization of base class objects must not be destroyed by deleting object of derived class. That is base class destructor must not be called upon calling derived class destructor.

If object of derived class is created, then constructor of derived class is called automatically, and if base class constructor has same name, then it is called also.
Same scenario will be happened if Destructor of base class is not virtual.
so it should always be virtual.
Same scenario will be happened if Destructor of base class is not virtual.
so it should always be virtual.
