Hard/Easy is a matter of relevance, not subjection. Morality on the other hand is the opposite, name 1 example of an objective moral position. You can't, even people living within the same culture can't agree.
no they're subjective.
for proof of their subjectivity, I offer you my disagreement.
since we disagree = they are subjective.
morality has an objectivity at its core (as does hard or easy or quality or truth) but people only grasp at it
subjectively. charity (as good) or murder (as evil) as you mentioned, are areas where people have come closer to this objectivity, not randomly but through reason.
by example:
a car runs a stop light and hits a kid on a bike and speeds off.
three people (witnesses) are interviewed by the police.
one says, "it was a black man driving a white Mustang"
a second says, "it was an arab man driving a yellow Camaro".
a third says, "it was a white woman driving a red Nova."
All have had a subjective experience of the hit and run, but their subjective experience of the hit and run does not negate the objective hit and run.
