How would you describe the poem’s tone, the poet’s attitude toward the characters and subject in "We Real Cool"?

It is of course possible for any work of literature to
have two tones or more, depending on its length and content. I think it is fair to say
that, thinking about this excellent poem, that there are two tones that we can pick out.
The defiance and arrogance of the speaker at the beginning of the poem is characterised
by such lines as:

We real
cool. We

Left
school...

The speaker
obviously feels proud of the way he has left school and is engaged in various activities
like "singing sin" and "lurking late" and this is an impression that is reinforced by
the alliteration used throughout the poem. However, the very last line, with the way
that the enjambment emphasises the word "die," adds a sad, sombre tone as the speaker
realises the results of the kind of "cool" lifestyle he has
chosen.
