Actually, the terrifying, calculating perception Daekol gained of Lex wasn't entirely accurate. That wasn't to say that he wasn't calculating, or calm, or that all of this hadn't been a part of his plan. It was just that he also hadn't faked his curses, and he really had been excited to beat up Daekol.
The reason why, at the moment, he looked so terrifying was because he had to use a lot of his focus and energy while turning his second phase from a mere concept into reality. The immense shock caused by Lex onto Daekol caused him to evaluate Lex's behavior into the same categorization as himself.
Thus, in every one of Lex's actions and behaviors, he saw a deeply sinister intent.
Lex, meanwhile, was checking the state of his Absolute Domain. One very important reason that he had changed his original plan of pulling Daekol into his self created realm was simply because of how easy it was to destroy realms.
