The God's plan theory scares me

What the hell some people have miserable life ,they haven't money,they are bullied despite them acting well even tho without being a Christian and relying on their own personal values?While other people who are complete asshole and douchebag they end up even an amazing life,married,a career on politics..a lot of Christian will tell you that God has a beautiful plan for everyone,they will also tell that if you pray you will receive but at the same time others will say God isn't like a magician🤦‍♂️🤦‍♂️some will also say that if a tragic event happened to you you should give your life to Christ and will also tell it's because you don't believe enough....

At this point I think Christianity is a form of gaslighting...

And even if there's a God I highly doubt they care about the world and their sons...
