It is a fairly useless analysis because the author (a software engineer) has no knowledge whatsoever of the terminology that the texts are using, nor their context. He's running a program on English translations.
For example, it is true that the Qur'an ceaseless calls Allah "merciful" (literally "Rahman"). But why? Mercy implies *guilt*, that he was going to smash you, but has (like a good tyrant) decided to be kind. Allah, in the Qur'an, is barely restraining himself from annihilating everybody with hellfire. That's why he is merciful. You are guilty, and you should pay, but Allah shall forgive you and extend you his mercy. Here, for example, are all the uses of terms in the Qur'an equivalent to 'mercy':

Just look at 'em.
"
Indeed, those who have believed and those who have emigrated and fought in the cause of Allah - those expect the mercy of Allah. And Allah is Forgiving and Merciful."
Another simple example:
And obey Allah and the Messenger that you may obtain mercy.
Now, one could say this is pleasant, or one could actually look at these references and say holy fuck, why is Allah constantly talking about how he shall be merciful and forgiving to those who obey him? And why is he merciful to believing jihadis who have fought for Allah? It's all about divine punishment, and its avoidance by submission to God's will. None of this can be resolved by simply taking the word 'merciful' and assuming it means something like 'loving,' when in context it normally means that Allah mercifully forgives the submitting believers of their sins .... unlike the non-believers, who he will smash for their disobedience and sentence to eternal hellfire. They get no mercy.
Likewise, the New Testament certainly talks a lot about killing ... but it condemns it. To take numerical frequency of such references as meaning that the text is 'violent' is a logical fallacy equivalent to taking an anti-war protestor to be pro-war because they talk about war so much. It is, I suppose, superficially true that anti-war protestors talk about violence a lot, using words like 'war' and 'killing'. Does that mean they are super-violent? Only if you are profoundly confused.
