Stay with the logic Graph, if you do then your questions are easily answered. The fact that Hammurabi didn't write the Bible shows that the lex talionis was indeed widely known and not used as a literal exchange but typically as a monetary one. The fact that Lamech was not godly is given as an example to show why such laws are necessary. Jesus does not preach "universal love" in the sense of withholding just punishment forever, he preaches more hellfire than anyone; Yahweh does not preach love for (that Jewish word) "genocide" but preaches (to Moses) that he is compassion even as he punishes at due times (i.e. not lightly, or literally not simply to punish). The reconciliation of these two is that actual love for all things means letting those beings go who confirm themselves in rejecting all love for a lifetime, and giving them the one thing they want, freedom from all aspects of love besides existence.
