Humanism in science fiction often shows through characters' moral dilemmas. For example, in 'Blade Runner', the replicants question their existence and rights, which reflects humanistic ideas about identity and equality.
One example is 'Ender's Game'. Ender shows compassion towards the 'buggers' he was initially trained to fight. This shows a humanistic side as he questions the morality of his actions and the value of other species.
It's hard to say. You might need to check with the publisher or look for specific information about the comic's translation status. Sometimes, it could be available in multiple languages, but it varies.
