#2 Why he should: Money

Goldberg means money - of that, there is little doubt. When his DVD was released by WWE in 2014, it sold over 100,000 units as he was among the four stars – alongside The Undertaker, The Rock and CM Punk – to achieve this honor.
Going by this, it shows that Goldberg draws, and when someone attracts money like that, it is only natural for WWE to extract any and all financial value from such opportunities. It is no surprise that WWE will indulge in this practice again, whilst giving Goldberg a fair shake for a one-off show.

#3 Why he shouldn’t: Adds nothing creatively to WWE

This. Part-timers like Goldberg add nothing to the company creatively - not in the long run, and in most cases, nothing beyond the spectacle of their return. WWE can’t build storylines around them and have to make-do by sticking together bits and pieces.
For example, Seth Rollins had virtually no storyline with Brock Lesnar heading into WrestleMania. He had just earned the right to compete for the title by winning the Royal Rumble, and there was no pre-existing grudge between the two. Rollins' eventual win was met with relief that Lesnar's run had ended, rather than any sort of creative payoff. So, in the long term, squandering story for 'OMG Moments' isn’t really a good thing.
