Strictness and hardship is good if it can shape you to face difficult situations in life but excess of it in your childhood or adult life can lead to some mental instabilities. I have seen such examples in life suffering from hardships in their life ending up suicide or became mental.
I am grown up in a strict environment but luckily it turned out to be good for me saving me from bad companies and many more like that.
People have all sorts of experiences I guess, some are positive and some negative...I think it's up to the individual to turn them into what they want them to be.
