We need to decide what to do with him. He was in one of the top TTP positions as a spokesperson and as such is responsible for the killing of hundreds if not thousands of Pakistani civilians and soldiers. Anyone can surrender when the going gets tough. It does not absolve the person however of his or her severe crimes against humanity. Also there is the potential that Ehsanullah may again revert to terrorism.
I am not sure what should be done but it shouldn't be easy for Ehsanullah, just saying he has renounced violence after killing so many innocents. Why was he part of the TTP anyway. Where was his honor and shame when he was killing our people mercilessly and speaking for the terrorists? Now suddenly we are supposed to believe that after being in a top TTP position he has given up violence just like that. Every angle should be investigated. Also Fazlullah is the main target. Kill him and we will celebrate.
