Holding a group of people responsible for the actions of their much more powerful service providers (whether that service is religious or banking) is unsound and is the point that was being made. It would be helpful to analyse this from an abstract point of view.
"they have some kind of intent in doing wrong and require forgiveness" This is another example of where your limited knowledge of the subject leads you to misconceptions.
Forgiveness in a Christian sense is not selfish, it is not motivated by self-interest. It is also not granted unless the person forgives others. For if you forgive others their trespasses, your heavenly Father will also forgive you, but if you do not forgive others their trespasses, neither will your Father forgive your trespasses.
There is also the matter of repentance. God does not typically forgive if he has not first granted you repentance - that is something that a person cannot determine on their own. Therefore, your notion that people can simply ask for forgiveness as part of an evil plot is nonsensical to those who are religious.
"or they require some kind of imaginary person in the sky to blame for going to war, killing" We have been through this already. Blaming god for such actions is using his name in vain and breaks one of the 10 commandments. Religious people are quite aware of the 10 commandments, it is taught to them at an early stage in their journey.
"someone who chooses to be involved in something because they are easily deluded" "or they just plain are attracted to some fetish they have - one that harms others" Those traits are not exclusive to religious people and not all religious people share those traits. In many cases, a person is brought up at home to follow a religion, so it is implanted during their childhood when they are more open to suggestion. It would not be fair to consider them easily deluded in such cases.
While you listed many negative reasons that you believe that someone would become religious, you failed to provide any positive reasons, which would have gone some way to balance your bias: -They made grave mistakes in their life and became a Christian to guide themselves towards being a better person. -They believe that people have been misguided by the materialistic world around them and want to promote Christianity as a way to give direction to "lost" people. -It is a family tradition and they want to one day have a family like the one they grew up in.
If you knew about Forgiveness and the 10 Commandments beforehand, you may have a better understanding of the framework in which religious people operate. As originally mentioned, I think jumping to conclusions about religious people being "very dangerous" without rudimentary knowledge of their religion is unwise.
