One thing would do it for me. One thing only.
Anyone who lies, cheats, betrays, steals or in any way harms anyone will instantly dissemble dissolve disintegrate disappear. Into thin air. That's it. All the bad apples with worms will be tossed and destroyed AUTOMATICALLY. That's the deal. Comply or die. 24/7. No exceptions. No do-overs. No Mulligans. Do it right or never get a chance to do it again.
How many people would "POUF" disappear before all others realized how the world worked and complied or else? Noncompliance would mean automatic "death".
Could you be happy in a world where people helped one another rooted for one another supported one another were honest with one another? Or would it be your WORST NIGHTMARE?
