Two completely different beasts. People saying Ralph is the "new Chris-Chan" don't understand Chris that well and are falling for a classic trope of declaring someone to be the new Chris. just because that person is silly.
Chris, more than anything, was gullible. "Naive". A lot of what people remember about Chris was something trolls talked him into doing. Very little of Classic Chris was just something Chris wanted to do. Chris wanted to sleep all day and play video games and have a girlfriend take care of his ever need. Trolls used girls to convince him into doing everything Chris is famous for -- except for fucking his mom, which is more debatable.
Ralph, more than anything, is narcissistic. His overinflated sense of self-worth, defensiveness, laziness and entitlement, are all components of his narcissism. His actions are definitely his own and nobody is telling him to do these things. He's very easily persuaded into doing stupid things with the slightest provocations, but that's not the same.
He's losing control, so to regain control he shit-tests his allies. Nobody has any reason to put up with him so they leave. He considers that proof they were never loyal to begin with, and that his tactics are successfully culling true enemies from his life.
People think that "X is a huge L" but to Ralph it's not. Metokur didn't come on anymore. Gator made fun of him. Rekieta's success didn't convert to Ralph's success. He can't just be friendly with people who's association doesn't directly benefit him. All these people are worthless to him because people are only conduits of giving him what he wants. May and Faith gave him children, which are only important to him because in online discussion having a family is important. He will never contest Xander's paternity because he doesn't want to pay child support. He will kick May and her child out out the second he's bored of them.
Ralph has nothing to lose. Nothing. He does not care. May could blow her brains out right now and he wouldn't even cry. Her parents would be the ones paying to cremate the body. As long as he's got about 200 people giving him $10 on average each month to enable his lifestyle, habits, and vices, Ralph will truly believe he is a winner.
