I suppose it would. But that isn't really that difficult, is it? For something to be meaningful, it has to bring something worthwhile to the world. If it contributes nothing of value, or worse, actively subtracts from or destroys the worthwhile things in the world...then that would be meaningless. I suppose it's not as simple as good or evil, because even murdering someone could be meaningful if it was someone who made the world less worthwhile by being in it. And helping someone could be meaningless, if that person only spreads despair and misery.

Still, it should be easy enough to know if you're spreading hope or spreading despair.
