I pray God gives him wisdom on how to best help people.
Otherwise he’ll donate the entire sum to climate change activists or something.
He can best help humanity by registering to vote and vote for conservatives and, if he donates to non-profits, ensure that the recipients are conservative organizations. If I were he, I would try my best to hook up with some Spook who can get him a new identity with all the back stories and pocket litter and anonymous accounts. Probably won’t get it here but maybe from an Israeli organization.
