"Do not go gentle into that good night"

"Do not go gentle into that good night" by Dylan Thomas
In the stanzas three, four, and five they talk about how some people approach death
Stanza three is how good men go towards the light. They seem to go towards heaven but they feel that they were not allowed enough time to accomplish more in their lifetime.
Stanza four is how wild men take death. THey do not have enough time to do what they want to. they live for each moment doing crazy things.
Stanza five is the Grave men. THey are accepting it but feel like it is unfair.
Over all everyone dies at some point and no one wants to so they keep fighting for what they want to do and never give up.
