Expressed well, yes. Letting it rip, no. There's supporting research that shows that unconstrained expression of anger is not a good plan. If you want to trawl medical papers for details, this one's a good starting point: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4824648/

(Note - you want the referenced papers, not the actual paper itself, which I consider weak-ish)

This is, theoretically, part of becoming an adult: Becoming aware of your emotions, and learning to express them in a healthy way. (Not just anger). Our society spectacularly fails us on that subject. We do extremely little to even explain what emotions are and how they influence it. (There's a reason "Inside Out" was a huge hit - it's one of the few pop culture pieces trying to do that job)
