Do all Christians believe all non Christians go to hell?

About a month a ago some guy approached me with a flyer saying something like “the only way through heaven is through Jesus, it doesn’t matter how good you were without him since we are all sinful.”
This really bothered me because I believe in God but I haven’t committed myself to any religion because I feel like they are all Corruptible and tainted by human lust for power and control.

All major religions teach much the same moral values and ethics but according to this guy I spoke to all Muslims, Buddhists, Hindus, and Atheists will burn forever when they die.
Christians believe God is all loving and Benevolent but then turn around and say “if you aren’t in our club God will burn you forever no matter how good of a person you were.”

If you are Christian do you believe all non Christians will go to hell when they die.

In my research I found that some Christians believe in the concept of Universal Salvation for everyone.
Universal salvation means that everyone no matter what they believed or how they lived their life will eventually repeat and go to heaven.
If you have done evil you will get punishment but that punishment will only be finite until you repent.
I think this Doctrine makes much more sense in my opinion.
