Let me take a stab at answering your questions:

No.

Maybe.
No.
No.
Not unless you're starving.
No -- you're helping to ensure your lineage survives.

Not if it doesn't bother you -- this is why we need police and jails.
No -- that's why it's important to show people that the handouts hurt everyone eventually.
Thank you for your answers. You demonstrated that this concept of "rationality" is completely faulty.
