The Innocent Keep Dying

97 people were killed and over 400 others injured after two powerful bombs went off near the main train station in Ankara, the Turkish capital this morning where a peace rally calling for an end to the renewed conflict between the Kurdish PKK organization and the Turkish government.
About 14,000 people were in the area as at the time of the explosion. Two suicide bombers are believed to have caused the blasts. Following the attack, for which no group has claimed responsibility.

Just like what is happening in Nigeria, which I got some questions; 

How do human beings derive pleasure by taking innocent lives? 

Why don't you kill those hurting you instead of the innocent? That would have made little sense.

Either way what we need is Change!!!
