Can A Person With More Merits Than Sins Go To Heaven?

Can A Person With More Merits Than Sins Go To Heaven, like Manis Friedman and YY Jacobson? Rabbi Yaron Reuven says, a person's sins must be dealt with first. But if a person is a Machti et HaRabim (someone that causes others to sin), the Rambam says, they have NO SHARE OF THE WORLD TO COME (unless they do SERIOUS TeShuva).
