ことにはならない

ことにはならない is used to deny the assumption or expectation that something will happen or be the case. It signals that a certain outcome is not decided, guaranteed, or inevitable, even if other factors or conditions exist. It often follows a clause that might lead someone to think the result is fixed, but the speaker asserts that it is not the case. This is common in everyday situations where plans, outcomes, or obligations are not set in stone. Note that the pattern focuses on negating a state or decision rather than expressing a general possibility.
