wow - that's a great question. I wonder if anyone (but a T) could understand the reason why unless they feel it themselves.
You said, When I cut I feel as if I'm releasing the bad in me and it eases the anger/tension I feel at the time.
This makes sense to me, and I think it is a good explanation. Your husband may not be able to understand this, and it is probably scary for him to see you hurting yourself. Do you see a therapist? - because I was thinking if you did maybe you could take your husband to one session and the T could help explain to you husband and help him understand how to deal with it.
Best wishes to you, and welcome to PC.
