These "rat catchers" do not magically change from a saint to a selfish liar and hater once voted.
They have always been of a selfish character throughout their history and that is really hard to hide for long.

I have head more than once argumentations from people voting such leaders basically boiling down to stuff like this:
- "Even if he is a liar, had sexual interactions with prostitutes, commited tax frauds, cheated his business partners, hates foreigners, ... he still is the only way forward."
- "I do not care who he is as a person, but he will take this elite society down that has ruined us. This country needs a cleansing fire to later be built from scratch again."
- "No matter what, things need to change. With the other guy everything would have stayed the same. So I rather vote an extremist than accept the status quo."
- "We need somebody strong to lead us into a new age. If he is not the most moral person or the most honest, I do not really care."
- "He promised, he will protect our jobs. Everything else does not matter to me and I am not even interested to hear it."
- ...
Such voters vote for such leaders because they do not care about morals, truth or integrity anymore, because they are fed up, discontent or even desperate.
They would even vote for a pig in a ballerina dress as long as somebody told them that it serves their goals and that pig would "Make ... great again !"
