It sounds correct to me. The only shortcoming is that the word "others" refers to two different groups of people in close succession. If this is an important phrase, rewriting it more clearly is not a bad idea.
Maybe something like
Some were made to cry, others to cause crying.
or, since this sounds a little formal,
Some were made to shed tears, others to cause tears to be shed.
You can subsitute your favorite synonym for crying (weeping, lamenting) if you want.
Some were made for lamenting, others to cause lamentation
I don't know the nature of your comic so I can't guess how formal/lofty/poetic you want it to sound.
