I don't think Louis will ever really recover from this (though I don't really care if he does or not, and certainly think people are valid in thinking he shouldn't) because his brand of humor is kind of contingent on him not being a shitty person.
A lot of his jokes can be boiled down to "I did a fucked up thing. It was a fucked up, harmful, dirtbag thing to do, and I shouldn't be like this," and it can work when there's just a sense of rapport between him and the audience, a sense of "yeah, that's wrong, let's do the right thing," but a lot of that charm is lost whenever we, as the audience, are instead going "Yeah, but you ARE a dirtbag."
That said, a good amount of the leaked material of his is just bad. Some of it I might be willing to chalk up to a comedian workshopping his material, but some of it has me like come on man :/. Like there is maybe some way to get some humor out of what he did if handled in a clearly self-deprecating way that makes it clear that he understands (and is telling his audience) that it was fucked up and that it shouldn't have happened to those women, but going out and instead framing it as "yeah I did it. I'm weird, okay?" is just bad in a variety of ways. It's not funny, and it's just gross to seemingly dodge the gravity of his actions.
