Some people try to anthromorphize the christians as a scheming group that have total conscience of their actions as detriments, but this way of thinking is actually quite counter-productive because it insufficiently addresses the problem of historical perspectives. If you were to look at many of the groups which have been reproducing negative ideologies throughout history, you would find that many people have never been explicitly antagonistic: it's that they were incapable of seeing that their actions were wrong in any way.
For example, many Christians during the Middle Ages did not somehow know in the backs of their minds that persecuting "blasphemers" was wrong, yet did not care enough to do anything about the issue: they genuinely believed that blasphemy warranted floggings, imprisonments, and murders. Simultaneously, every generation of people believes that they are lucky enough to be living in a society which is the most enlightened of all history. They believe that they have the best perception of the world out of anyone, and that they are not fundamentally fallible.
That's why the concept of Hell isn't just "fear tactics" anymore; it's a actual perspective, delusionally made into reality in the mind of many. And, due the fact that every major organized religion conflates morality with their mythology, christians see the act of reprehending people thorugh fear as a virtuous pursuit. Morality is like that in general: It is always an instance of people with power contriving arbitrary ideals to justify actions, or adjusting their actions according to their arbitrary ideals. In conventional Christianity, killing yourself would intuitively be desirable because you would be able to go to heaven. In Buddhism, taking five seconds to kill yourself would free you from a lifetime of suffering. And yet in both, suicide is arbitrarily forbidden for contrived reasons.
