Christianity is poison, because it preaches weakness and torment as the path of truth. It destroys a person's mind and does not allow him to live his own full life.
Why only Christianity? Every religion is a means of enslavement of the people. All the activities are intended to live at the expense of believers. Religion is more of a vampire than poison. It is not profitable to kill the victim. It is advantageous for it to parasitize.
Christianity is the only religion that offers eternal life to all who believe it. Jesus died on the cross, and arose on the third day, to remove sinfulness from people. The only reason people die temporarily, is to remove their sinful thinking from themselves. All people will arise from the dead in the resurrection on the last day.

Regardless of religion after death, people are not resurrected like a zombie, just their soul is separated from the physical body and sent to the world of the dead.
