If it means you don't have to leave your kids alone as it starting to get dark or having to take a collosal **** somewhere other than your own toilet then hell yeah it's justified. If he wanted to commited suicide he could've done it in the comfort of his own home where he doesn't have to ruin everyone's day except his own family's.
When you're at the point of committing suicide you don't think about anything but actually doing it...
Taking a dump or getting somewhere a little late is no justification of telling someone to kill themselves. Geez you people are all about yourself aren't you? Wonder what your opinion would be if someone in your family went through with something than that.
