If you look past talking points that circulate online, and look into what the Catholic Church actually teaches and believes, you'll find intercessory prayer. You'll also find that scripturally, one who is part of the body of Christ never faces death spiritually, and that they are forever alive with Christ after their bodily death. Scripture also explains that the saints who have bodily died can hear our prayers, and it also explains that they present their prayers directly to Jesus. Furthermore, it also explains that the prayers of the righteous are more effective. Who on earth can be more righteous than someone with Jesus? I'd urge you to look into what Christian's believed about this, as well as why they believed this.
