How annoying is that Levi kid?

That kind of illustrates the point exactly.

I cannot say without knowing the crime.

I have less respect for someone who acts blindly on the word of another, whatever the context. I have more respect for someone who breaks the law to feed his child than one who breaks the law to fulfill some arbitrary text written centuries ago.

Any evil act that requires religion to justify it is just made worse by trying to make that argument in my view.

The religious person every time.

The chaotic criminal might not have a reason, probably doesn't even need one. There's only a base desire to do something that society has deemed illegal, and it was carried out by one individual seeking his or her own self satisfaction in that base desire. Someone without a reason isn't bothering to do a self-examination, they just do it.

The religious person has a reason, and it must be a good one too to willfully go against the laws of men. Religions are always preaching self-inspection with one hand, but duty, shame, and guilt with the other. But they're not alone. How many people taught that person to be religious? Who twisted printed words in such a way that condones illegal activity? Who will praise the action and count the criminal as a martyr? And most importantly, how many will follow in his footsteps?

On the small scale, Person A carves his initials into a bathroom stall. Who cares really? he was there, he was bored, everyone after him knows that. He might even get creative and write a limerick or draw something obscene. It might make the next person giggle, but it's harmless. Person B carves a cross. Still harmless and nobody cares, but he's not just announcing his presence. He's using the symbol of an ancient torture device to proselytize to a captive audience and even annoy 70% of the world's population that isn't Christian.

Taken to the extremes, basically we have a serial killer vs. a suicide bomber. Serial Killers have the occasional copycats, but it pales in comparison to the countless bombers who carry out indiscriminate killings in the name of religion and the institutions that endorse future tragedy.

Neither is better or worse, it's not the motivation, but the end result. It doesn't matter if you murdered someone for god or you just want to see what it's like to kill someone, you've deprived someone of life.
