People can't give what they don't have. Those who have not received love will not give love either, although of course, that is not the absolute reason for that behavior, since it would exonerate from responsibility those who steal, cheat, or those who are corrupt, there are many other reasons for them to be like this, but yes , this is one of them.
Thank you very much for your appreciation @irenenavarroart, and I take this opportunity to congratulate you for your creativity in asking these questions. Have a great weekend. Hugs too!
