Since when did something being law make it just?
Incorrect, even in US cities it can be seen with high gun controls (Chicago) vs barely any controls.

..thus the reason why gun crime is so high is an unintended consquence of gun controls. With gun controls, you may have 10 would-be criminals who will arm themselves, break into a house and out of them 10 incidents it may result in 4 of them ending in death.
Without gun controls, of the 10 would be criminals, 6 may be instantly put off even considering breaking into private property and of those 4 incidents that take place, 2 may end in death (but with a twist, the deaths resulting from those incidents would include the criminals as opposed to the innocent occupiers of the property).
Gun control logic is always simple and thus is easily disproven with a little thought (unintended consquences).
Or I could stay here and argue for more freedoms and the right to self defence?
It is true that accidents will happen, of course you are correct. Which is exactly why we deserve, as adults, the right to be able to make our own choices and take our own risks - just as you take a risk everytime you may go skiiing, cross the road, take drugs, go on a booze cruise and so on.
