Isn't causality a disproof for the Copenhagen interpretation In QM, each measurement result cannot be predicted, in other words, that is random. This being random has a great implication: if there is no rule to specify the results, so there is cause. This lack of cause is not something acceptable logically. In other words, the non-deterministic (that is stochastic) NATURE of, let's say, electrons, means that there is not enough causes to determine the results of the observations (so electron decides where to go for itself). So, how can one resolve this contradiction between the orthodox viewpoimt of QM and the causality conjecture?
 A: I am not sure exactly what you are getting at, but there are a few misunderstandings in your post.
For example, "...so electron decides where to go for itself" is not how electrons work. Electrons are governed by physical laws, which provide a set of states that the electron can exist in. We may not know which state the electron is in before measuring, but neither does the electron. Once any measurement is made (including the electron measuring where they are), the answer is known.
More generally, measurement results are "random", but each possible result must obey the laws of physics - and one of those laws is causality. So every possible state that a particular system can be in does obey causality, even if we don't know which state is it before measuring.
In principle, theories of quantum gravity might have causality-violating states, in the same way quantum mechanics has states which violate classical mechanics. People are working on that:

A: You, the OP, are right.  According to the Copenhagen interpretation the future is not predictable, because measurement is inherently probabilistic. 
Here are some references that mention the problem of non-determinism (acausality) inherent in the Copenhagen interpretation: Stanford.edu, utm.edu, and Oregon.edu.
The Many-Worlds interpretation is a frequently cited resolution of the apparent contradiction between QM and causality: it asserts that all possible futures coexist in the wave function.  The wave function itself is deterministic, although individual particle trajectories are not deterministic.
In the Many Worlds interpretation the future wave function is still unknowable (due to the uncertainty principle which makes exact measurement of a wave function impossible), so the future of the wave function is not predictable even though it is deterministic.
