In Judah-ism
Talmud, Seder Nezikin, Bava Metzia 59a:2 (same context as the Oven of Akhnai mentioned in Bat Kol):
One who engages in intercourse with a married woman before witnesses and with forewarning, his death is by strangulation, but he still has a share in the World-to-Come. But one who humiliates another in public has no share in the World-to-Come.
This means that sinners also have a part in the World-to-Come as long as their sin is not too grave.
Talmud, Seder Nezikin, Sanhedrin 90a:15 (right reference, quoting Miqra):
הֲדַרַן עֲלָךְ אֵלּוּ הֵן הַנֶּחְנָקִין
מַתְנִי׳ כׇּל יִשְׂרָאֵל יֵשׁ לָהֶם חֵלֶק לָעוֹלָם הַבָּא, שֶׁנֶּאֱמַר: ״וְעַמֵּךְ כֻּלָּם צַדִּיקִים לְעוֹלָם יִירְשׁוּ אָרֶץ נֵצֶר מַטָּעַי מַעֲשֵׂה יָדַי לְהִתְפָּאֵר״. וְאֵלּוּ שֶׁאֵין לָהֶם חֵלֶק לָעוֹלָם הַבָּא: הָאוֹמֵר אֵין תְּחִיַּית הַמֵּתִים מִן הַתּוֹרָה, וְאֵין תּוֹרָה מִן הַשָּׁמַיִם, וְאֶפִּיקוֹרוֹס.
MISHNA: All of the Jewish people, even sinners and those who are liable to be executed with a court-imposed death penalty, have a share in the World-to-Come, as it is stated: “And your people also shall be all righteous, they shall inherit the land forever; the branch of My planting, the work of My hands, for My name to be glorified” (Isaiah 60:21). And these are the exceptions, the people who have no share in the World-to-Come, even when they fulfilled many mitzvot: One who says: There is no resurrection of the dead derived from the Torah, and one who says: The Torah did not originate from Heaven, and an epikoros, who treats Torah scholars and the Torah that they teach with contempt.
