Loneliness and being alone are different. But for Tom, that doesn't matter. For someone who’s lived a life without much of a parent’s guidance, Tom grew up thinking he was alone and that nobody really cared. He recognises the fact that, yes, he may have been acquainted with other people, but he has made no genuine friends at all. This stems from his perception that people needed to change themselves to fit in and be accepted, which just didn’t make sense to him. He grew tired of living the routine and nature of everyday life and eventually succumbing to the idea that no one will even notice when he’s gone. In the end, will he realise the gravity of his actions early enough to pull himself together or will it be too late for him to redeem himself?
