Nope, that's pretty much it. #1, in particular, seems important.
Important to whether it is murder, but not to whether something was killed, unless I am missing something.
I suppose "bullet" may have been a poor choice, as there may be too many cached associations with murder, but bullets can certainly take life in situations we view as morally justified - in this case, defense of others.
Suppose I have choice between the following:
A) One simulation of me is run for me 100 years, before being deleted.
B) Two identical simulations of me are run for 100 years, before being deleted.
Is the second choice preferable to the first? Should I be willing to pay more to have multiple copies of me simulated, even if those copies will have the exact same experiences?
Forgive me if this question has been answered before. I have Googled to no avail.
