In the many worlds interpretation of Qm, is there one universe in which I am a horrible murderer, for example?
After you commit (theoretically) your first horrible murder the universe will split another infinity times. So there will be an infinite number of them.In the many worlds interpretation of Qm, is there one universe in which I am a horrible murderer, for example?

Lol... also, maybe ?... there is one universe in which you are just aWhether you do this or that in some alternative universe is not specified by the interpretation, which leads to much (pointless) argument.
It depends. The MWI says that, whenever a measurement is made on a quantum system that is in a superposition of eigenstates of that measurement, the universe splits into multiple copies, one for each eigenstate, i.e., one for each possible measurement result. (Here "result" doesn't just mean the new state of the system, but the state of the measuring device, of all the people who observe the device's output, etc.) So for there to be a universe in which you are a murderer, there would have to be some kind of quantum measurement process like that involved in the events that led up to your being a murderer, or not, depending on how the measurement came out.In the many worlds interpretation of Qm, is there one universe in which I am a horrible murderer, for example?
I should also mention that there is another issue here, namely, what defines "I" in this hypothetical? In other words, suppose that there is some alternate MWI branch in which there is a horrible murderer; how do we know that that murderer is "you"? Presumably that person will have a very different personality and history from the "you" that posted the OP in this thread. So what makes them count as the same person?is there one universe in which I am a horrible murderer
Who gave you this premise of infinity? That's not true, it would be divided a finite amount of times, if the interpretation was correct, in quantum theory discrete regions of space have finite amounts of energy. The probability of DNA-based life is greater than zero; and if the number of types of DNA-based living things is finite (because the size of the DNA molecules cannot be arbitrarily large ,the number of possible histories in each region is finite because the energy in each region is finite and, according to quantum mechanics, energy is quantified.After you commit (theoretically) your first horrible murder the universe will split another infinity times.

That's not correct as you state it. What is correct is that some systems (basically, bound systems) have discrete energy levels; but others (such as free particles) do not. Also, even most bound systems with discrete energy levels have an infinite number of them, so you can't conclude from the fact that the energy levels are discrete that a measurement of energy can only have a finite number of possible outcomes, which is what you would need to conclude to make "it would be divided a finite amount of times" true.according to quantum mechanics, energy is quantified
Yes - everything consistent with the boundary conditions and laws of physics happens. Loosely speaking, everything possible happens.In the many worlds interpretation of Qm, is there one universe in which I am a horrible murderer, for example?
If we have two indivduals, then one presumes both individuals continue to exist in the splitting of their respective universes. It becomes difficult to track any individual or to count the universes in which they exist when all possible splittings are considered. Without specifying some kind of counting procedure your argument is speculation.Who gave you this premise of infinity?
