Because their life revolved around war. There was a political king, and a war king at all times, and the war king could have easily had the political king killed he wanted to. It wouldn't have a happy ending, but it was certainly a big possibility. The war kings weren't exactly known for their intelligence outside of battle.

In 460 BC, the helots, who were the subjugated population of Sparta, nearly succeeded in a major uprising against their Spartan overlords. This revolt, known as the Helot Revolt, was fueled by discontent and the desire for freedom, particularly during a time when Sparta was preoccupied with external conflicts, including the ongoing wars with Athens. The revolt posed a significant threat to Spartan stability, but ultimately, the Spartans managed to suppress the uprising, maintaining their control over the helots.
Rebellion was a constant threat in Sparta primarily due to its reliance on a large population of enslaved people known as helots, who vastly outnumbered the Spartan citizens. The harsh treatment and oppression of the helots fostered resentment and the potential for uprisings. Additionally, the militaristic nature of Spartan society meant that any signs of discontent could quickly escalate into rebellion, prompting the Spartans to maintain a strict and often brutal control over the helots to prevent insurrection.
The revolt (which was crushed) caused Sparta to realise that they needed an army ready for battle the entire time if they were going to control the vast number of Helot slaves. So all men (and women to some degree) trained for battle and Sparta became the most feared fighting force in Greece.

Sparta's population was mostly slaves, and their economy depended on slave labor. A slave revolt would certainly be economically devastating, and there was a distinct chance that the slaves would win and overthrow the Spartan government, so obviously this was always something Sparta was worried about.
The slave revolt in Sparta, known as the Helot Revolt, began around 464 BCE, triggered by a significant earthquake that devastated the region. This natural disaster weakened Spartan control and provided the Helots, who were state-owned serfs, an opportunity to rise against their oppressive conditions. The revolt escalated into a prolonged conflict, as the Helots sought to assert their freedom and challenge the Spartan authority. The Spartans ultimately managed to suppress the revolt, but it highlighted the tensions between the ruling class and the Helots.
