A Poison Tree a poem by William Blake?

The poem 'A Poison Tree',by William Blake is a emphatic depiction of the consequences of repressed feelings and emotions in human beings. Blake is trying to show how dangerous wrath can be. The wrath the speaker has towards his friend is spoken of and quickly dissappears. However, the wrath towards the enemy does not get released, and it brings with it much negativity. So from this poem we learn that it is always better to express frankly, or to give up if possible, all our hatred and evil notions towards others.

This saves us from all misdeeds towards others as well as ourselves. or he eats a poison Apple...
