The abstract noun "anger" is spoken of as it it were something that usually could be held in a container, but in this situation there is so much of it that what does not fit needs to be spread around. It is also a metonym for the actions a person takes when he is angry. You may need to make explicit why the person is angry. Alternate translation: "Be angry because people are proud, and punish them" (See: [[rc://en/ta/man/jit/figs-metaphor]] and [[rc://en/ta/man/jit/figs-abstractnouns]] and [[rc://en/ta/man/jit/figs-metonymy]])
