Why did the wooers defer the plot to murder Telemachus?

The wooers deferred the plot to murder Telemachus primarily due to their fear of repercussions and the uncertainty of the outcome. They recognized that Telemachus had recently embarked on a journey to seek news of his father, Odysseus, and they worried that harming him could provoke the wrath of the gods or lead to retaliation from Odysseus himself if he returned. Additionally, their political ambitions and desire to maintain a façade of respectability made them hesitate to commit such a drastic act.
