But there are a lot of things that exist that aren't exactly friendly. People often hinge their belief or disbelief in any divinity singularly on the bible. They consider proof of God existing is based on whether all the claims made in an old book are true - not that it is a fallible piece. It either has to be all true or all false which is not how any scientific text more than a decade out of date has proven.
Not saying that means anyone should start praying. The God as listed in the Bible given their behaviour does not seem either omniscient, omnipotent or benevolent but those ideals have shaped a lot of the discussion about whether something classifies as a "true" God or not. A lot of thought and debate goes towards squaring that circle. Sometimes the easiest answer is that lies exist. The presense of other gods are noted in the bible. Maybe that one was just a super powered Narcissist.
There's a very specific rubric for what counts as a terrorist attack in Canada. Probably the level of calculation and premeditation involved was a factor and that he's not a part of an ideologically organized group that is trying to influence behaviour of a government or political body.
A spontaneous hate crime made against a population is technically not a terrorist attack by Canadian definition. To count you have to have done it for a narrow slice of very specific reasons.
