Jesus seems to forgive people for serious criminal behaviour.

Correct!
Yet this statement you meme is a 2 part series in context:

"And Give To God That Which Rightfully Belongs To God."
The money coined belongs to Ceasar for taxation, ones Heart and Soul belong to God if and when one grants it to Him.
The Things that are YahWeh's came from Righteousness and Love.
Jesus not only seems, yet Possesses the Power to Forgive All Sins, even Serious Criminal Behavior;
yet one must first acknowledge ones shortcomings in humility, ask for forgiveness, and meekly seek reconciliation to possibly receive such. In Him, ALL things are possible.

now lets talk about this in a different context....what if it was render Putin what is his? render CCP and Mao what is his? Render Stalin what is his, render Hitler what is his? Its a really naive way of percieving power and money and kind of dangerous for all of us on earth. Its dangerous to just ALLOW dictators to do whatever they want and turn the other cheek when they do it. We'd all be slaves under certain dictators. Its not smart, intellectual or stwed in with much common sense to RENDER dictators what is theirs. Ceasar killed millions of people adn TOOK land...his money....is from murder. You should never ever forgive murderers, it makes society extremely dangerous. Like Dahmer was baptised, why would you even want an evil spirit like that in your heavenly paradise?

Money is a creation of man, not a creation of God. $ is of this world, not of the next.
Pretty Sure an evil spirit such as Dahmer will be left without an invite to the Party, yet I'd let God sort that out.
