To execute someone, you must first be either a king or queen in Bitlife, as it is a right reserved for only the highest rank of royalty. When you are in this rank of royalty, the option to execute people in Bitlife will become unlocked.
However, you will suffer backlash from citizens if you execute too many people at a time, so it's probably a good idea not to go crazy with it. Along with that, you can also get random events where you must decide the fate of someone with an option to execute them.
That being said, if you want to execute someone as a king/queen, start by creating a character in one of the countries listed below.
- United Arab Emirates
- Saudi Arabia
The countries listed above all have royalty, and each will have a random chance to have you born into the royal family. We recommend rerolling characters until this happens or try marrying into the family.
After all that, you will then need to wait until the current king/queen dies or find a way to remove them from power. Once you are the highest rank in the royalty, you will be able to execute whoever you want via an option under royal activities.
