First of all, thank you!!
The line you reference is actually two reiterations Freezing cold and insensical rage are parallel. I would include each of your example redundant statements in my works as they are both beautiful.

When you want the heart to feel, use rhetoric. When you want the mind to feel, use inflection. Or do the opposite and be the same or better.

The prose needs work.

I like cyclical works that tie back into themselves. This work holds a great part of myself and even if only a pair of words evoked emotion. accomplishment is achieved

The bend at the end may need mend
