It turns out Karmakilla was proud of what the TF2 community accomplished with the Golden Charity, and wanted to contribute as well.
Not content with everyday good deeds like helping old ladies cross the street and helping runaway criminals out of their chains, he and his brother organized their own fundraiser. They wanted to leverage the unified power of the Golden Wrench, PAX, Jerry Holkins (aka Tycho), and the alignment of all 8 planets to maximize the publicity and donations. Surely, these Biblical-level titans could somehow wrangle up $500 for Child’s Play in one day. Right?
