First, be killed casually.
The status of slaves is very low, if any slave is killed by other slaves on the road. Slave owners will not seek justice for their slaves, as long as other slave owners give him some money as compensation, so as slaves in ancient Rome, they are in danger of losing their lives at any time.
Second, die in the Colosseum.
Ancient Rome had a very bloody hobby. They like to watch slaves fight with slaves in the Colosseum, or watch slaves fight wild animals. In the process of fighting, there will always be a slave who loses, and the slave who wins may get a little reward. If the failed slave had not died in the Colosseum, his slave owner would have killed him.
Third, generations are slaves.
Once you become a slave, you will never turn over. The identity of a slave is fixed from the moment of birth. You can only work for the slave owner in the field like a talking animal. The children they gave birth to also continued to work for slaves and their own slave owners, leading a hopeless and miserable life from generation to generation.
The above three points are the tragic fate that ancient Rome would face as a slave. Slavery is a very barbaric system in the process of human civilization. Fortunately, this system was finally abolished.
