Cyril cheated on Lana primarily due to his deep-seated insecurity. This personal flaw led him to engage in sexual relationships with multiple women at ISIS.
The Driving Force: Insecurity
Cyril's infidelity was a direct result of his own internal struggles with self-worth and insecurity. Rather than being an act of malice towards Lana, his actions stemmed from a personal inadequacy that compelled him to seek validation or reassurance through sleeping with other individuals within the organization. His decision to cheat was therefore a manifestation of his own vulnerabilities and lack of confidence.
Consequences for Their Relationship
The discovery of Cyril's cheating profoundly impacted his relationship with Lana. Her trust was shattered, leading to a significant deterioration of their bond. While Lana's subsequent actions involved misleading Cyril about her own supposed infidelity (where she had men pay her to claim they slept with her), this was a direct reaction to Cyril's betrayal. Ultimately, Cyril's insecurity-driven cheating was the catalyst that officially ended their romantic relationship.
