Morals and values means honoring the contract YOU agreed to. It means when YOU sign a contract, YOUR WORD is sufficient to guarantee you will make each and every payment ON TIME.
Apparently you don't have the morals and values to make those payments on time and the lender took the steps to protect their interest.
As you throw around terms you don't have any idea how to use, it is obvious you do not have any understanding of how financing works. When thje car is repo'ed, that doesn't end your responsibility. (Why not look up the definition of the word "responsibility"). You signed a contract. They are suing you for the amount of the contract.
You were a SUB-PRIME borrower prior to this transaction because of your reputation of NOT paying your bills on time. And ONCE AGAIN, you continue in your sub-prime ways.
Why not change your ways???
