And we all know how Christ Treats his enemies...
43 "You have heard that it was said, 'You shall love your neighbor, and hate your enemy.'
44 "But I say to you, love your enemies, and pray for those who persecute you
"I have come NOT to bring peace, BUT THE SWORD."
Paul tells us to judge just judgment, and that the GOVERNMENT IS THE SWORD OF GOD.
Assassination is perfectly moral.
