Is Purin/Pudding Evil???

Is Charolette Pudding evil or nah??? I happen to think so. I just can't find myself to trust her given she's apart of Big Mom's crew. That doesn't necessarily mean she is evil or one of the bad guys. I mean she was born into the crew. She has been shown to help the Straw Hat crew when they arrived in Totland. Why would Purin save Luffy and Chopper from being arrested? She asked for their names even though she should recognise them. Could this be Big Mom controlling her or is she playing along. Brook points out sweet she is, as most people after reading that chapter thinks she is. Every scene she comes off as sweet and innocent. Maybe that's how she really is. She kind of reminds me of Sanji how she explained in detail she made some chocolate with her recipe in chapter 827, seems like she loves cooking. After meeting the Mugiwaras in the chocolate town Im guessing Pudding notified Big Mom of their arrival if Big Mom didn't already know. Or it could be homies and thats how she keeps tabs and gains intel on people.
Purin saves and helps the SHs only to put them in danger. Either way their presence was known to Big Mom. During a scene with trying on a dress it seems like shes trying to get away to meet up with the SHs. If she was so nice enough to show Luffy and gang a way to Whole Cake Island, why not warn them about the seducing woods? She could have drawn them a map just to save herself from Pedro killing her. Some things just don't make sense with her. She probably knows she's under constant surveillance and has her reasons for witholding certain info. Purin doesn't want to end up like Pound lol. Also I cant wait to find out if she is the girl with the third eye or is it her twin sister? Oda needs to hurry up and confirm if shes really good or not.
