Deleted. Just read some responses and realise my thoughts and beliefs will upset some people.
ETA I've finished reading all responses and to be honest I don't understand the different between 'meant to be' or 'fate' or 'luck of the draw' and 'that's just life' type sentiments. It sounds like semantics to me.
Horrible things aren't exactly 'meant to be' but given most of the time they're out of someone's control or choice or understanding, or unfair or unjust or just plain devastating, what else can you possibly call it?
