We do not point accusing fingers at any culprit. But we know there is a God who knows and sees all things. And it's basic in God's law that asks for respect for life. In the fifth commandment is: "Thou shall not kill" (Ez. 20:13; Mt. 19:13). Even kidnappings violate the substance of the Law and the Prophets: "Do unto others what you want others do unto you" (Mt. 7:12).
What's the reason then for the above happenings? Maybe revenge or desperation. But it is not the right answer. The end does not justify the means You cannot right a wrong with another wrong.
Let's not forget. There is a God who sees and knows everything, even the secret intentions of the heart. The Son God who came to our world had said: "Never repay evil with evil but let everyone see that you are interested only in the highest ideals. Do all you can to live at peace with everyone. Never try to get revenge; leave that, my friends, to God's anger. As scripture says: Vengeance is mine -- I will pay them back, the Lord promises. But there is more: If your enemy is hungry, you should give him food, and if he is thirsty, let him drink. Thus you heap red-hot coals on his head.
Resist evil and conquer it with good (Rom. 12:17-21). Don't forget what God's word says truly, "He will punish man for any evil he does" (Deut. 32:35).
