Ergo the reason why it's fine to let it happens.

Plus, Tangle have to do what Sally failed to done in the past; learn her lesson. And Tangle got infected because she rushed ahead, failing to heed Jewel's warning, like multiple times. So once she got cured from the virus, she will start to listen to Jewel's powerful advice.

Also, the reason of Tangle got infected served a purpose to draw in more characters that hadn't pick up the idea or clue of what the heck went on with the Zombot Apocalypse. As I listed few characters from before: Knuckles is safe from the virus, unless Flicky Bird decided to visit his island; Blaze wasn't seen since Sonic left her with Tangle to turn off the fire; Tikal and Chaos Zero hadn't introduced in the comic yet; and so on.
