Why are we so angry? Who are we angry at? Sometimes our anger is directed at the person who died. But we can be angry toward a range of people, including doctors and even God. This anger is motivated by something different than anger we feel toward the person who died. If you take a toy away from a toddler, he may scream at you in anger. And sure enough, sometimes you give him the toy back, because you see how much it has upset him. But no one can return the person who died.
