You say that illegals are people who broke the laws, but that's a big simplification.

For example, the law says that people who have close family living in US and being US citizen are allowed to apply to become US citizen themselves. To do so, they need to come to the US to apply and be present to answer the questions when their file is progressing. But this process is slow and can take years before they even start reviewing the case due to delays. So, for these people, 1) in few year, the administration will say "oh, yes, we concluded that you perfectly have the right to be here", 2) the administration requires them to stay close, so, to live in the city they are applying. And right now, they are now illegals.

In other terms, the only way for them to not be illegal is to be illegal for a while. And once they have been illegal for a while, they may became legal, which is a way for the administration to say "well, turns out that you had the right to be here all along".

On top of that, some people who tried their best to follow all the process still become illegals just because the administration was too slow or did not inform them of the correct procedure (or inform them of the incorrect procedure). It is simply unfair of you they say "these illegals are bad people not following the rules" when in fact they really want to follow the rules but somehow the rules break and someone says "oh, too bad, you did absolutely nothing wrong, but now people can point the finger at you and treat you as if you are a bad person".

Sure, this is not the case for all the illegals. But this is also a huge incentive for illegals to not even bother to try to become legals: why jumps to all the hoops and spend energy if anyway even when you should be granted the nationality, you are still considered as illegal and take the same risks. The system is broken and people don't see the point of following an unfair process.
