Did Obama really say he could do whatever he wanted, after all, he is the law?

First half yes, 2nd half no.
The statement should be taken in context, and also considered to some extent that the President does have certain authorities. The statement was about his ability to see Monticello, the estate of Thomas Jefferson from a private terrace despite the fact that it is a breach of protocol of protecting the President.
Lines from the Bible are often taken out of context badly to create things and views that don't exist.
In your own reference:
"Mr. Obama made the tongue-in-cheek remark as he toured Monticello, the Charlottesville, Va., estate of Thomas Jefferson, with French President Francois Hollande. The visit is part of Mr. Hollande’s three-day stay in the U.S. this week.
The president delighted in his ability to “break the protocol” and view the Monticello grounds from a private terrace.
“That’s the good thing as a president. I can do whatever I want,” Mr. Obama said.

"Mr. Obama’s pronouncement came just an hour after the administration took unilateral action to delay and trim back more of the employer-mandate portions under Obamacare, the latest example of the White House’s willingness to act on its own, even when it comes to changing laws already on the books."

Now, the Republicans and most Americans do not support the AHCA (Obamacare) anyway, so if he acts to delay things he is supporting the Republicans and I cannot see that as worthy of criticism.

If he acts against the laws of the land as properly enacted and judged, there is an issue.
