I think that the misuse of this new ability in using against Gabriel is nearly suicidal in my opinion because she was naive in her reactions but if she wasn't Gabriel would give Issei the treatment that Jiraiya in Naruto actually gets, and Gabriel is very powerful, and her Holy power is rather strong the beating could be dangerous to Issei.

I think that Issei should count his blessings that he wasn't castrated for doing this, and if Michael didn't react badly towards him remember Gabriel is his sister, and what Issei did is considered a lewd act a sin to them, and he had every right to administer a serious punishment towards Issei but I am sorry what he did is really dumb in my opinion.
