I always pretended to be a gentle spirit.
Yet to stubborn to realize I exceeded my limit.

*I like how you started this. I like thw two line style,Very simple.

It planted the seed and watched it grow,
And my hate soon overflowed.

*Shouldn't It be I? I like how you chnage emotions here, I want to know why you hated the tree. Nice*

Something sinister was growing inside me,
implanted there by Destiny.

*Love the diction here*

It made me a monster.
Killing all who opposed me.
Burned it all and watched it fall.

*This stanza has alot of emotions, but it ruins the flow of things, I'd work on trying to make it two lines like the rest*

My heartless tyranny was always a seed of sadness,
but soon blossomed into a Tree of Madness.

*Wow, what a powerful ending. Very nice work. Keep it up. Nik*

I love the whole concept in this piece, it was very dark and captivating. Excellent emotions and depth, this was a fantastic write! The suspense and how you entranced the reader really made this an enjoyable yet a bit scary poem. Keep up the excellent work, and good luck with writing, you are on a great start! Take care and God Bless You!
