Well done for posting the numerous Old Testament verses, it takes a good while to find all those.
But what about all the New Testament?
Matthew 5 v17 "Do not think that I [Christ] have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfil them."
Matthew 5 v43 "You have heard that it was said 'You shall love your neighbour and hate your enemy.' But I say to you, Love your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heaven....(v46) For if you love those who love you, what reward do you have? Do not eben the tax collectors do the same? And if you greet only your brothers, what more are you doing than others? Do not even the Gentiles do the same? You must be perfect, as your heavenly Father is perfect."
The time before Christ was different, and the Law (especially Leviticus) is the old Jewish law. The reason so many of them call for the death of those involved was to show the people the seriousness of their actions and how that the failure to follow God's law demands death, but the message of the Gospel is that Christ rescued us from this punishment by taking it upon himself.
I stand by the Ten Commandments
"You shall not murder" Exodus 20 v13
It sums it up for me
I'll post some more in a bit when I've finished looking stuff up
