The core of philosophy is basically understanding consciousnes, not too much else to it. But I guess one page was an exaggeration, let's say five.

There is no "core of philosophy", and it's certainly not confined to "understanding consciousness". I'd have to agree with others here who have tried to admonish you that you're arguing from ignorance and being unserious, even if a great deal of what passes for philosophy is a waste of time. What about logic, philosophy of mathematics, philosophy of language, ...?

Asking what is good or bad is like asking what is the definition of these words. Well, the definition is whatever we agree on. IMost people call "bad" the behavior, that triggers specific emotion of "wrongness".

I think that consciousness and closely related topics is the hard part, other things such as ethics or aesthetics have quite mundane explanations. Philosophy of mathematics nad language is somewhere in between.
