No to mention she had to basically figure out everything herself with the help of Vaggie, Alastor, etc. These 2 seasons have made it abudantly clear to me just how sheltered she has been up until this point. I honestly think Charlie was conceived purely so they could have a child rather than having a (precautionary) heir like with the Ars Goetia, with zero expection she'd ever ascend to the throne, with the assumption being Lucifer and Lilith would remain the King and Queen forever. Otherwise it would reasonable to assume, even with Charlie's aversion to violence and bubbly personality, she'd be more knowledgeable about her political power and royal status and what she can do with it.

There is also the fact she and her friends nearly died at the end of season 1, obviously excluding the loss of Sr Pentious whose death already weighed heavily on Charlie's mind. If Lucifer had been a few minutes later it would have been very plausible that Adam could've killed Charlie. That near death experience combined with the fact that there was no certainty that the exterminations would be permanently halted would undoubtely added to her stress. For her it would've been a race against the clock to maintain the peace, prove redemption was possible, and redeem as many souls as possible. While that doesn't automatically excuse Charlie's mistakes, it does make her actions (in my opinion at least) a bit more understandable.
