I do pray. Often.
But I have stopped saying "you're in my prayers" because, honestly, many times when I said that, I would forget to pray for the person. So, I wanted to stop appearing "pious" and if that person comes to my mind while I'm praying, I pray for them. If they don't, I won't have lied telling someone I prayed for them when I didn't.
But I do need to pray more for people, even those I don't know. So if I remember his family (I don't pray for the dead) when I'm on my knees, I will say a prayer for them in their time of bereavement and grief.
As a standing policy, I don't rejoice over those who die. I don't care how evil, immoral, "stupid," "deserving" they are. I just find that repulsive. Yet, I see it a lot on social media, people rejoicing over the death of someone.
My rule is consequences speak for themselves. If you're breaking into someone's home and you can shot and killed, I don't have to say, "Ah, ha! He got what he deserved." The consequences speak for themselves. I don't need to rub salt in a dead person's fatal wound. What happened, happened. If he got what he deserved, then let the consequence speak for the both of us.
Truth be told, if you had the same background, life experiences, struggles and desperations others had, you'd more than likely do the same thing. Just be thankful your experiences, upbringing, moral foundation, environment, era in which you were born was different than someone else who met a tragic end.
And get your soul ready for it is appointed unto man once to die then after ....
