They are afraid that ghost will tempt Hamlet to hurt himself
Well, think of how young people are today. Think of yourself even.
To be critical, young people today are quite self-invested, while they want a change in the world, they don't have the motivation to do the work to change. They have many wants, but they simply don't have the motivation or will to do it. Charity is giving to the homeless, helping the needy, or rebuilding or even just feeding someone. Charity can be for so many things. Young people are all about bettering themselves, and not others first. They will not openly give their food to a starving person on the street or give them money to go and buy their own -- they will simply walk on and not glance in their direction. So think basically, charity is giving. And young people today are essentially greedy, right? This is the key thing it wants you to talk about - go into detail.
