What is one of the biggest things that made you begin to question Christianity!

For me i have a lot of reasons why but it was mostly getting critical thinking and reading the Bible with that thinking, and realizing that god is a narcissistic piece of shit; and also the fact that god made jesus go to that cross as much as he didn’t want too go and cried about it, but god still made him when he couldn’t have like taken all the sins of humanity and helped his son..? what a all loving god!! it’s all a fucking sham, Christian’s are brainwashed bro..
