Why does murdering children imply you should receive no sympathy? Is sympathy only an emotion for the morally clean?

»We all have choices and free will [...]« is debatable. There are probably better times to do this but it is definitely debatable.

Isn't free will he flip side to determinism? I am able to generate truly random numbers which are completely non-deterministic by any number of methods (deck of cards, pick a number 0|1 over and over, muscle twitches, etc). Doesn't that imply that I have, at some basic level, free will?

It could just as easily imply that your decisions are essentially random noise, which we seek to rationalize afterwards.
