I have read the manga and watch the anime, Beerus is like that at all.
I don't know how many times I have to repeat myself for you to understand perfect English, but I guess I will do it again.
Beerus couldn't kill Zamasu because of his immortality which would regenerate all of Beerus's attacks. Zamasu doesn't have a resistance to EE and can still be affected by Hakai. That's why he was still being erased, but Zamasu's Regenerationn would stop Hakai from killing him. Goku wasn't able to kill Zamasu with Hakai, he was able to effect Zamasu because Zamasu lacks any resistance to EE.
That is your own headcanon that is completely baseless. Zamasu could have grabbed Mai for a number of reasons, like I don't know, to get Goku to stop trying to erase him? Just because you can regenerate a wound doesn't mean obtaining that wound doesn't hurt.
You do know that the wiki considered the manga's Hakai to be matter destruction and not EE, right? Mainly because there was seemingly no quote about Hakai in the manga destroying souls - until now that is.
I already explained the proof. Every other version of the media considers Hakai to be EE, and now with this quote from Beerus saying he would destroy Frieza's soul, it would imply the manga does as well. Occam's Razor points to it being the only attack in the series that was shown to destroy souls - Hakai.
Unless you want to say that regular old Ki attacks affect the soul.
Beerus never does any of the shit that you say. He doesn't bluff and he doesn't kid about his own power. He has never ever insinuated that he would do something that he couldn't do. If said he would destroy Frieza soul, then he would destroy it.
