The study you quoted is statistically flawed. They ignore other factors that may effect crimes such as presence of a powerful alternative to death penalty, and whether the death penalty is actually enforced in the State or not. There are similar studies that have been quoted but there are many more studies than that which say, no conclusion can be drawn from these statistics. The consensus amongst criminologists is that Death penalty does not have a deterrent affect on violent crimes.
As for Pakistan, if you look at the number of deaths of civilians and security forces. The number of deaths actually increase significantly after the death penalty is reinforced in 2012.
Also, the death penalty is not the only variable that effects terrorism in Pakistan. The changes in the number of deaths can be due to unemployment, poverty, military operations, changes in enforcement, actions of Americans in Afghanistan etc. You need to study statistics my friend. Cant draw black and white correlation while ignoring everything else in the world.
OK! May be I am using a different Google then!

Our results suggest that capital punishment has a strong deterrent effect; each execution results, on average, in 18 fewer murdersówith a margin of error of plus or minus 10 -
Paper: I hope you understand statistics:

- We can debate that for which crimes capital punishment should be used! e.g. I'm against using it for Blasphemy. But it needs no rocket science to see how much terrorism went up in Pakistan when Capital punishment was abolished in 2008 and how much it has come down since it has been re-instated!
