Being a lolcow is a choice. These people want attention and online infamy. It stimulates the massive ego that basically all of them have. Chris Chan, Wingsofredemption, DarkSydePhil, Low Tier God, YandereDev, and SpoonyOne all claim constantly that "The fuckin Trollz" are ruining their lives and that they're nothing but evil, sick, cyberbullies. They bitch and moan about them nonstop and belly ache about how they'd be soo much happier without the trolls "ruining everything" for them.
It's a fake victim mindset really. They claim that they want the trolls to stop, yet they constantly make fools out of themselves, and they put no effort to change themselves because they KNOW deep down they'd be nothing without them, so they CONSTANTLY give them attention. Continuing the cycle endlessly for more views, clicks, money, and attention.
Occasionally certain lolcows, (for example Sammyclassicsonicfan and Mariotehplumber) turn out to be trolls, or at the very least turn their lives around and stop acting like fucking retards. Others get arrested and basically yanked from the internet for their abhorrent behavior (like Nick Bate). You could also argue that some mass shooters are "failed lolcows" in the case of people like
@FuckYou and Randy Stair. Both those dudes are definitely lolcow material, they just never really reached that point and instead they chimped out.
Generally speaking, if a lolcow is aged 18ish or older, there really is no hope for them to ever be a "Normal" person or live a normal healthy life. They'll always be fucked in some aspect. These people are everywhere: Gang Members, Drug Addicts, Incels, Pedophiles, Radical Militants and Terrorists, only difference is they (usually) don't engage in stupid internet fame shit.
TLDR: Lolcows are to point and laugh at, nothing more, you cannot change them.
