Final answer:
Julius Caesar did punish pirates for their pirating activities, capturing and crucifying many of them.
Step-by-step explanation:
According to historical accounts, Julius Caesar did punish pirates for their pirating activities. In 67-66 BCE, Pompey the Great was appointed to put down the pirates across the Mediterranean. Caesar himself was captured by the pirates and held for ransom, but after his release, he gathered a fleet and successfully captured and crucified many of the pirates. This punishment sent a strong message and helped to curb their activities.
