Initially, EOKA was intimidating the population not to co-operate with the security forces, but steadily the definition of traitor broadened as the security forces had some successes EOKA at the end of 1956. EOKA members who had spoken to the security forces under interrogation were also considered as traitors and Grivas was in favour of the death penalty in such case. Incidences happened where EOKA guerrillas killed others by their own initiative and not solely based on accusations for treason. The killings took place in public. Such activity peaked especially during summer-autumn 1956. The Greek Cypriot Left and in particular the communist party (AKEL) were also targeted. The later aimed at a political role in the Greek Cypriot community challenging EOKA's claim that Makarios was the sole leader of the community. As AKEL was growing in numbers it was practically denying Makarios' role. The British delicately fueled this hostility and in August 1957 a second wave of intra-Greek violence broke out. Due to intimidation methods and targeting civilians towards local population a number of scholars characterized EOKA as a terrorist organisation. Another similar wave broke out in April- October 1958 when a peace agreement was imminent. AKEL held massive demonstrations and sought the help of Makarios which he granted.
