Hmmm, maybe informing Asgore was the original plan, but then Sans showed up suggesting a different plan and he was the one injected with DT, wich would explain why he was so powerfull... Also, they can keep track of timelines to some extent. Asgore absorbing six souls wouldn't be safe at all because they can rebel against him. Maybe Sans had that much confidence that he would manage to handle problem himself, so he tought there wasn't need to warn Asgore.
