Another expression for very many people. It most commonly used to justify certain acts such as in 'it benefits the All'. Usually, however, there are quite a lot of people such an act will not benefit, and most likely you are one of those.
It is considered to be very noble to do things for the All, unless the All does not want to be helped. The All are usually very conservative and might get quite upset on people who try to help them, such as Jesus Christ.
Even though the All are a bunch of selfish idiots, you should try to help them even it they resist your aid. They need it desperately.
