Christian is an umbrella term that describes many differing sets of beliefs. This is an oversimplification but Protestants for example believe in Sola Fide, the believe that salvation comes from faith alone (https://en.wikipedia.org/wiki/Sola_fide), whereas Catholics believe that salvation requires "good works", the sort of thing you're likely thinking of. So ... different groups hold differing sets of beliefs with regards to what loving your neighbor means and what is expected behavior. This is a huge oversimplification, the "Salvation in Christianity" (https://en.wikipedia.org/wiki/Salvation_in_Christianity) and "Good Works" (https://en.wikipedia.org/wiki/Good_works) pages can help orient (or disorient) you.

“Protestants” are not a monolith and can have very different ideas. And no, I was not thinking of good works, it’s more general than that. The New Testament is all about being merciful, letting go of hate and not seeking retribution. How we are supposed to act on those ideals is not always clear, but that is a recurring theme in the foundational book of all Christian denominations (the big ones anyway).
Anyway, that was mostly rhetorical. The actual reason is that religion is just a way of making a point without having to support it, the ultimate appeal to authority. These people are happy claiming that Jesus loves people, except for some scapegoats, whom he hates. It’s pathetic, really. I have a lot of respect for people who actually live in accordance with their principles, even if I don’t agree with them. None of the Christian I know who are like that support the death penalty.
