Poem about Judas....?

I'm analyzing a poem for class and it's about Judas (one of the apostles who betrayed Jesus).

Or at least I hope so, I'm not Christian so I know very, very little about Judas and his story etc.

I just wanted to know if I'm understanding the poem correctly. I was a little confused by the soldiers and by the last few lines..

This is what I gathered: Basically Judas was going to kill himself but when he saw a man being beaten, he immediately forgot about his own problems and ran to help the man despite all the soldiers that were after him.

So yeah, basically I just wanna know if that's the gist of the poem? Thanks xx

Anyway here's the poem

Saint Judas by James Wright

When I went out to kill myself, I caught

A pack of hoodlums beating up a man.

Running to spare his suffering, I forgot

My name, my number, how my day began,

How soldiers milled around the garden stone

And sang amusing songs; how all that day

Their javelins measured crowds; how I alone

Bargained the proper coins, and slipped away.

Banished from heaven, I found this victim beaten,

Stripped kneed, and left to cry. Dropping my rope

Aside, I ran, ignored the uniforms:

Then I remembered bread my flesh had eaten,

The kiss that ate my flesh. Flayed without hope,

I held the man for nothing in my arms.
