To some. Not everyone likes cupcakes. But sure, it’s just an example.
Well, are pleasure and suffering really all that different? May there not be a very thin line between the two? Still, I agree that there’s indeed a line between them.
Yes, that’s kind of what I meant by that parenthesis about mental health. Mental well-being, motivation, etc.
No, this is nonsense and doesn’t follow from the aforesaid. Causing suffering to another need not cause suffering to oneself and may even give pleasure to oneself.
That’s at best intersubjective, not objective. Is sociopathy bad, mentally unhealthy, or dysfunctional? Not objectively. It’s funny that you are kind of the “libtard” here, asserting things like this. Also, like your “categorical difference” between pleasure and suffering, it’s quite superficial.
