At least nobody can say Allah is not the same God . Or what do you want to say? Anyway that is whataboutism. Christianity is another topic. But while you are at it, I would add: Fundamentalist Christians dont kill others because of that bible verse. That is the difference. The islamistic terrorists do that. The problem is that Muslims consider the koran as a holy book. But they dont realise that it is distorted or simly false because of the contradiction. So it cannot be a holy book. Only one part can be true. Either the part that says: you have to kill others or you dont have to kill them. Because the koran has both in it, it is false. There are a lot more contradiction in this book. The difference of the old and new testament is similar to the difference of the medina and mecca surah. Those surah of medina have far more evilness in it than those of mecca. And those of mecca are far more inspiring than those of medina. The old testament also has also far more of the evilness than the new testament. And the new testament has far more positive and inspiring verses. Of course also the old testament has inspiring and positive verses. It also depends on the books of the old testament. Because of the contradictions I rather follow Jesus teaching then some random non-elaborate laws from i.e. Moses or Muhammad: Love thy neighbour as yourself and love God with all your heart. That is a true teaching also one that the old enlightened masters taught before Chritianity or Islam even existed.
