So rather than just take the drugs following a burglary - which would leave her in the clear, mind you - she decides to get involved in the murder?
Honestly, that's just as bad as if she were involved in the murder in the first place. It makes her no less a party to the murder.
You are not understanding her entire motive. It was also to fool Filomena into thinking a burglar took her drugs. If she just went in there and took the drugs without making it look a real mess and a break-in, she probably thought she would have been under suspicion. I think she liked her situation and wanted to keep it. She was even asking Filomena a few days later if they could still be roommates.
