Let’s start with recalling the definition of Friction. According to scientists, friction is a force that resists. So if seen superficially, you’ll think of it as what you called in your question “bad”. But, science says, not all resistance is bad. In fact, with the point of view of Physics, this resisting force is inevitable for quite a lot of our daily activities.

For example we are standing steady on the ground, that is because of friction,in this case friction is good.Now consider a heavy block is resting on the floor and you have to push it to some distance,you will require ample of force to carry out the work. In this, friction is resisting the work,hence it is referred as bad.
