I think DSP has brainwashed himself over the years to think he's a positive force and, due to his complete lack of self-awareness, is blind to the fact that he's one of the most toxic people on the internet. It all ties in with his e-hermit lifestyle, where he's literally talking to himself 8 hours a day, 6 days a week (let that sink in for a moment...), blocking any and all criticism, constantly retconning stuff from the past and coming up with up new "facts" that make him look good as a person. At some point the lies have become something he genuinely believes to be true, simply because he has repeated them so often.
I mean, it literally only takes a single "slow" stream for the real DSP to rear its head, and fling his toxic bullshit towards his one and only friend; the camera. In his own mind, this is him taking care of his "business" by begging and trying to defend it against anyone who has the audacity to have even the slightest form of criticism, but 90% of the people who are watching are seeing an angry near-40-year-old man who is living inside a self-made fantasy world, constantly running away from the harsh reality.
It's a sad story when you think about it, really.
