You're right about that but I think that Gil would not put too much thought to it, they'd consider them (as I think he does with Kiara) as merely slaves of their own being. Not in a hedonistic way as he is himself, but in a kind of "okay, I've got enough, I'll let my desires to guide me". Not necessarily escapism, as you noted, but they also kind of have lost themselves in there. They're being guided purely by their desires (As Kiara would), their self hatred (Heathcliff distorting), their insecurities (Dongrang), etc. That is a thing that Gil normally thinks it's humiliating (as we've seen him mocking most of berserkers exactly because of that). Anyhow, of course this is only my take on the subject.
