Justify morality?
Why should anyone have to justify having a sense of morality? This guy indirectly says so himself - it's an innate quality that has been pivotal to our survival and development. We don't need a God to give an avenue to justify it.
The first cause argument. The argument presented was just another appeal to a justification through ignorance. For example Einstein's theory of relativity describes a mathematical relationship between space/time and energy/momentum at the macro-level and fails at the micro/quantum level. It does not provide a solution to the first cause question.
None of what he said links an intelligent designer/ creator to a loving God who cares tracks every thought that we have etc.
Free will? This one is as perennial as the grass. If we have free will why do some continue to sin - and here's the important point - in spite of a will not to sin? Free will is just not cracked up to be what it is said to be.
