As long as the Hogyoku remained intact, Aizen Sōsuke's body could be endlessly recreated.
Unless Aizen Sōsuke's will or heart developed a problem, or the not-yet-fully-fused Hogyoku separated from him, sealing was the only way to deal with Aizen Sōsuke.
Thus, having reached this point, Chiba Makoto had no choice but to weigh how much possibility remained of forcibly subduing the supremely arrogant Aizen Sōsuke through sheer force.
