Well I can understand what you're trying to say but like think of it like this, someone has to suffer through grueling exercises and sticking to to their diet to reach x goal, did they suffer and was it hard for them? Yes they suffered but in the end they kept at it and they reached their goals. Not in all scenarios but there'll be instances when people have to suffer to get a goal
Well I mean humans take everything for granted until it's taken away from them there's no really specific reasoning for why, like here's an example. When you have a fever, sore throat, massive headache you'd be suffering wishing it'd just go away, but once you get all better, the next day you won't even take it for granted that you got all better you'd be like "oh now it's gone i'm just going to go on about my day" and that's like with everything in life..
There maybe a slight misunderstanding (sorry if thats the case), well like I said earlier yes I believe suffering is bad but that depends on the context. I can't speak to much on why god decided to create humans or not as I am not christian so i don't know anything about that
Sorry if there's a misunderstanding between us
