Well to me 'murder' implies no valid reason
theres no valid reason to kill no one but by accident or self defence
the word kill is less guilty than murder
imagine the case
some wackos take their hobby to far and take a real 109 and spit and dogfight over new york, i understand will be able to do this soon in the future

virtually of course
one kills the other
what would the newspaper read
a guy who lived in his mom basement took a plane and kill or murdered his friend
if you take a girl and make her fly this sim she will like it till people starts shooting at her
edit:
as youi see having fun making people think and waiting to jump online to from on a foes six at 10 m and no shoot
just be there to make him nervous
