How should we reply to people who say Allah made us to endure hardship?

Salam, I'm hoping to get some wisdom on this. It's pretty clear from the title, but I've even come across some folks who think extreme thoughts, like wanting to end all life to prevent more souls from facing trials in this world. SubhanAllah, that's a heavy mindset. What's the right way, grounded in our deen, to respond to this kind of claim about suffering?
