Calum Hood is very different from other boys his age. For one, he's very feminine, wearing skirts and makeup. His parents don't exactly like the fact that their son is not only gay but also dresses like a girl. Mostly due to his parents constant rejection, he feels like he's completely alone and this is where the suicidal thoughts come in. Ashton Irwin is a very angry person. This may be because he has to deal with abusive parents who don't like the fact that the "little bastard is a fag as well" (Their words, not mine) Due to this, Ashton converts all of his feeling onto anger, taking it out on everyone else. Honestly, he just feels alone and hitting people doesn't make him feel any better. And that is when the suicidal thoughts enter his mind.
