I can only speculate as we are lacking in context for a lot of what transpires in the trailer, though the impression I walked away with was that it was meant to be sleazy, horrific and unsettling. There is likely more to it than that, as we saw in the previous games. For example, what takes place in Fort Joy is also incredibly horrific but within the context of the setting it makes a large degree of sense even if one does not agree with the methods.
